Occasional Numbness

May 02, 2016 Widely known as sciatica, lumbar radiculopathy is pain, numbness, weakness, and/or tingling sensations that radiate (travel) downward from the affected level in the low back into the buttocks and legs. Some people experience pain in both legs, though one leg can be worse than the other. Nov 25, 2020 numbness, burning, or tingling in your hands or feet; muscle weakness in your arms, legs, feet, or hands; swelling, rapid weight gain, shortness of breath; signs of tumor cell breakdown-weakness, muscle cramps, nausea, vomiting, diarrhea, fast or slow heart rate, tingling around your mouth. Why numbness matters. By itself, occasional numbness may not be serious, because it’s rarely a result of brain and spinal cord problems. But, numbness combined with tingling or pain can indicate carpal tunnel syndrome or a more serious health issue, like multiple sclerosis (MS). Mar 31, 2020 Occasional, temporary numbness is normal. However, numbness that's frequent, persistent, or on just one side of your body could be a sign of an underlying condition, such as nerve strain or damage. Carpal tunnel syndrome is the most common nerve condition related to numbness in the hands and forearms.

Carpal tunnel syndrome is a common condition that causes pain, numbness, and tingling in the hand and arm. The condition occurs when one of the major nerves to the hand — the median nerve — is squeezed or compressed as it travels through the wrist.

In most patients, carpal tunnel syndrome gets worse over time, so early diagnosis and treatment are important. Early on, symptoms can often be relieved with simple measures like wearing a wrist splint or avoiding certain activities.

If pressure on the median nerve continues, however, it can lead to nerve damage and worsening symptoms. To prevent permanent damage, surgery to take pressure off the median nerve may be recommended for some patients.

Anatomy

The carpal tunnel is a narrow passageway in the wrist, about an inch wide. The floor and sides of the tunnel are formed by small wrist bones called carpal bones.

The roof of the tunnel is a strong band of connective tissue called the transverse carpal ligament. Because these boundaries are very rigid, the carpal tunnel has little capacity to 'stretch' or increase in size.

The median nerve is one of the main nerves in the hand. It originates as a group of nerve roots in the neck. These roots come together to form a single nerve in the arm. The median nerve goes down the arm and forearm, passes through the carpal tunnel at the wrist, and goes into the hand. The nerve provides feeling in the thumb and index, middle, and ring fingers. The nerve also controls the muscles around the base of the thumb.

The nine tendons that bend the fingers and thumb also travel through the carpal tunnel. These tendons are called flexor tendons.

Description

Carpal tunnel syndrome occurs when the tunnel becomes narrowed or when tissues surrounding the flexor tendons swell, putting pressure on the median nerve. These tissues are called the synovium. Normally, the synovium lubricates the tendons, making it easier to move your fingers.

Carpal tunnel syndrome is caused by pressure on the median nerve as it travels through the carpal tunnel.

When the synovium swells, it takes up space in the carpal tunnel and, over time, crowds the nerve. This abnormal pressure on the nerve can result in pain, numbness, tingling, and weakness in the hand.

Cause

Most cases of carpal tunnel syndrome are caused by a combination of factors. Studies show that women and older people are more likely to develop the condition.

Other risk factors for carpal tunnel syndrome include:

• Heredity. This is likely an important factor. The carpal tunnel may be smaller in some people or there may be anatomic differences that change the amount of space for the nerve—and these traits can run in families.
• Repetitive hand use. Repeating the same hand and wrist motions or activities over a prolonged period of time may aggravate the tendons in the wrist, causing swelling that puts pressure on the nerve.
• Hand and wrist position. Doing activities that involve extreme flexion or extension of the hand and wrist for a prolonged period of time can increase pressure on the nerve.
• Pregnancy. Hormonal changes during pregnancy can cause swelling.
• Health conditions. Diabetes, rheumatoid arthritis, and thyroid gland imbalance are conditions that are associated with carpal tunnel syndrome.

Symptoms

Symptoms of carpal tunnel syndrome may include:

• Numbness, tingling, burning, and pain—primarily in the thumb and index, middle, and ring fingers
• Occasional shock-like sensations that radiate to the thumb and index, middle, and ring fingers
• Pain or tingling that may travel up the forearm toward the shoulder
• Weakness and clumsiness in the hand—this may make it difficult to perform fine movements such as buttoning your clothes
• Dropping things—due to weakness, numbness, or a loss of proprioception (awareness of where your hand is in space)

In most cases, the symptoms of carpal tunnel syndrome begin gradually—without a specific injury. Many patients find that their symptoms come and go at first. However, as the condition worsens, symptoms may occur more frequently or may persist for longer periods of time.

Night-time symptoms are very common. Because many people sleep with their wrists bent, symptoms may awaken you from sleep. During the day, symptoms often occur when holding something for a prolonged period of time with the wrist bent forward or backward, such as when using a phone, driving, or reading a book.

Many patients find that moving or shaking their hands helps relieve their symptoms.

Doctor Examination

Physical Examination

During your evaluation, your doctor will talk to you about your general health and medical history and will ask about your symptoms.

He or she will carefully examine your hand and wrist and perform a number of physical tests. During these tests, your doctor will:

• Press down or tap along the median nerve at inside of your wrist to see if it causes any numbness or tingling in your fingers (Tinel sign)
• Bend and hold your wrists in a flexed position to test for numbness or tingling in your hands
• Test sensitivity in your fingertips and hands by lightly touching them with a special instrument when your eyes are closed.
• Check for weakness in the muscles around the base of your thumb
• Look for atrophy in the muscles around the base of your thumb. In severe cases, these muscles may become visibly smaller.

Tests

Electrophysiological tests. These tests will help your doctor measure how well your median nerve is working and help determine whether there is too much pressure on the nerve. The tests will also help your doctor determine whether you have another nerve condition, such as neuropathy, or other sites of nerve compression that might be contributing to your symptoms.

Electrophysiological tests may include:

• Nerve conduction studies. These tests measure the signals travelling in the nerves of your hand and arm and can detect when a nerve is not conducting its signal effectively. Nerve conduction studies can help your doctor determine how severe your problem is and help to guide treatment.
• Electromyogram (EMG). An EMG measures the electrical activity in muscles. EMG results can show whether you have any nerve or muscle damage.

Ultrasound. An ultrasound uses high-frequency sound waves to help create pictures of bone and tissue. Your doctor may recommend an ultrasound of your wrist to evaluate the median nerve for signs of compression.

X-rays. X-rays provide images of dense structures, such as bone. If you have limited wrist motion or wrist pain, your doctor may order x-rays to exclude other causes for your symptoms, such as arthritis, ligament injury, or a fracture.

Magnetic resonance imaging (MRI) scans. These studies provide better images of the body's soft tissues. Your doctor may order an MRI to help determine other causes for your symptoms or to look for abnormal tissues that could be impacting the median nerve. An MRI can also help your doctor determine if there are problems with the nerve itself—such as scarring from an injury or tumor.

Treatment

Although it is a gradual process, for most people carpal tunnel syndrome will worsen over time without some form of treatment. For this reason, it is important to be evaluated and diagnosed by your doctor early on. In the early stages, it may be possible to slow or stop the progression of the disease.

Nonsurgical Treatment

If diagnosed and treated early, the symptoms of carpal tunnel syndrome can often be relieved without surgery. If your diagnosis is uncertain or if your symptoms are mild, your doctor will recommend nonsurgical treatment first.

Nonsurgical treatments may include:

Bracing or splinting. Wearing a brace or splint at night will keep you from bending your wrist while you sleep. Keeping your wrist in a straight or neutral position reduces pressure on the nerve in the carpal tunnel. It may also help to wear a splint during the day when doing activities that aggravate your symptoms.

Nonsteroidal anti-inflammatory drugs (NSAIDs). Medications such as ibuprofen and naproxen can help relieve pain and inflammation.

Activity changes. Symptoms often occur when your hand and wrist are in the same position for too long—particularly when your wrist is flexed or extended.

If your job or recreational activities aggravate your symptoms, changing or modifying these activities can help slow or stop progression of the disease. In some cases, this may involve making changes to your work site or work station.

A steroid injection into the carpal tunnel may relieve symptoms for a period of time.

Nerve gliding exercises. Some patients may benefit from exercises that help the median nerve move more freely within the confines of the carpal tunnel. Specific exercises may be recommended by your doctor or therapist.

Steroid injections. Corticosteroid, or cortisone, is a powerful anti-inflammatory agent that can be injected into the carpal tunnel. Although these injections often relieve painful symptoms or help to calm a flare up of symptoms, their effect is sometimes only temporary. A cortisone injection may also be used by your doctor to help diagnose your carpal tunnel syndrome.

Surgical Treatment

If nonsurgical treatment does not relieve your symptoms after a period of time, your doctor may recommend surgery.

The decision whether to have surgery is based on the severity of your symptoms—how much pain and numbness you are having in your hand. In long-standing cases with constant numbness and wasting of your thumb muscles, surgery may be recommended to prevent irreversible damage.

Surgical Procedure

The surgical procedure performed for carpal tunnel syndrome is called a 'carpal tunnel release.' There are two different surgical techniques for doing this, but the goal of both is to relieve pressure on your median nerve by cutting the ligament that forms the roof of the tunnel. This increases the size of the tunnel and decreases pressure on the median nerve.

The transverse carpal ligament is cut during carpal tunnel release surgery. When the ligament heals, there is more room for the nerve and tendons.

In most cases, carpal tunnel surgery is done on an outpatient basis. The surgery can be done under general anesthesia, which puts you to sleep, or under local anesthesia, which numbs just your hand and arm. In some cases, you will also be given a light sedative through an intravenous (IV) line inserted into a vein in your arm.

Open carpal tunnel release. In open surgery, your doctor makes a small incision in the palm of your hand and views the inside of your hand and wrist through this incision. During the procedure, your doctor will divide the transverse carpal ligament (the roof of the carpal tunnel). This increases the size of the tunnel and decreases pressure on the median nerve.

After surgery, the ligament may gradually grow back together—but there will be more space in the carpal tunnel and pressure on the median nerve will be relieved.

Endoscopic carpal tunnel release. In endoscopic surgery, your doctor makes one or two smaller skin incisions—called portals—and uses a miniature camera—an endoscope—to see inside your hand and wrist. A special knife is used to divide the transverse carpal ligament, similar to the open carpal tunnel release procedure.

Here, an endoscope is inserted through a portal in the patient's wrist. A cutting instrument will be inserted in the palm.

The outcomes of open surgery and endoscopic surgery are similar. There are benefits and potential risks associated with both techniques. Your doctor will talk with you about which surgical technique is best for you.

Recovery

Immediately following surgery, you will be encouraged to elevate your hand above your heart and move your fingers to reduce swelling and prevent stiffness.

You should expect some pain, swelling, and stiffness after your procedure. Minor soreness in your palm may last for several weeks to several months.

Grip and pinch strength usually return by about 2 to 3 months after surgery. If the condition of your median nerve was poor before surgery, however, grip and pinch strength may not improve for about 6 to 12 months.

You may have to wear a splint or wrist brace for several weeks. You will, however, be allowed to use your hand for light activities, taking care to avoid significant discomfort. Driving, self-care activities, and light lifting and gripping may be permitted soon after surgery.

Your doctor will talk with you about when you will be able to return to work and whether you will have any restrictions on your work activities.

Complications

Although complications are possible with any surgery, your doctor will take steps to minimize the risks. The most common complications of carpal tunnel release surgery include:

• Bleeding
• Infection
• Nerve aggravation or injury

Outcomes

For most patients, surgery will improve the symptoms of carpal tunnel syndrome. Recovery, however, may be gradual and complete recovery may take up to a year.

If you have significant pain and weakness for more than 2 months, your doctor may refer you to a hand therapist who can help you maximize your recovery.

If you have another condition that causes pain or stiffness in your hand or wrist, such as arthritis or tendonitis, it may slow your overall recovery. In long-standing cases of carpal tunnel syndrome with severe loss of feeling and/or muscle wasting around the base of the thumb, recovery will also be slower. For these patients, a complete recovery may not be possible.

Occasionally, carpal tunnel syndrome can recur, although this is rare. If this happens, you may need additional treatment or surgery.

Tingling hands, often referred to as the pins and needles effect, is a common occurrence and is typically not caused by a serious condition. It is most often brought on by pressure being applied to nerves in your arm when you lean on it. This can occur when you fall asleep and lay your head on your arm. The tingling feeling usually goes away when the pressure is relieved.

However, sometimes pins and needles can be caused by something more severe and can become chronic. When this is the case, the tingling feeling can be accompanied by other symptoms such as numbness, pain and itching. This can be an indication of nerve damage caused by a wide range of ailments.

Causes of Pins and Needles in Left Arm

1. Poor Blood Circulation or Pressure

Improper blood circulation can happen when you sleep in awkward position and blood cannot flow properly through it. It can also occur when you are wearing a tight piece of jewelry like an arm band.

Tingling in the left arm can also occur when there is too much pressure applied to it. If it is intense enough, it may even go numb. If you have a pinched nerve in the area around your arm, you may experience tingling in your hands.

2. Vitamin Issues

Several vitamins are vital to proper nerve function, especially vitamins B1, B6, B12, and E. If you have too much vitamin B6 in your body, you can experience pins and needles in your left arm. However, if you don't have enough B12, you may have the same tingling feeling.

3. Alcoholism

Alcoholics often suffer from vitamin deficiencies because their disease causes them to follow poor diet habits. When this occurs and it affects the nerves, it is called alcoholic neuropathy. Damaged nerves can cause tingling and numbness in your arms.

4. Medicines

Sometimes certain medications can cause nerve damage, but in many situations their benefits outweigh their side effects. The good news is the damage is reversible once you cease taking the medicine. If you experienced tingling in your hands or arms, it will typically go away.

Occasional Numbness In Right Pinkie

Medications which are known to cause pins and needles in left arm are antiretrovirals for the treatment of HIV/AIDS, chemotherapy medicines for the treatment of lymphoma and breast cancer and metronidazole, an antibiotic.

5. Carpal Tunnel Syndrome

When you have to consistently do a repetitive motion or work at a computer for an extended period of time, nerves in your arm may get pressed and restrict blood circulation. When this occurs, you can experience numbness, pain and tingling in your hands and arms.

6. Thoracic Outlet Syndrome

When you suffer from poor posture caused by obesity, pregnancy, trauma and poor posture when sleeping, you can suffer from thoracic outlet syndrome. This condition occurs when the nerves located in the back of the neck, arms and armpits are compressed. Pins and needles in your left arm can be a symptom of the syndrome, as well as discoloration, pain and numbness.

7. Heart Attack

At any time you experience tingling in the left arm or hand and it is accompanied by pain in your chest and jaw, you should seek immediate medical attention. This could be an indication of a pending heart attack. You want to see a doctor right away to avoid complications or possible death.

8. Stroke

If you have pins and needles in left arm, it can also be a sign of a stroke. This is a very serious condition caused by a low blood supply to the brain, causing it to essentially shut down. Again, immediate medical attention is vital in this case.

Exercises That May Help

1. Acupressure

Acupressure is a type of treatment used to increase blood circulation. Pressure is applied on specific points of your body, lessening blockage in blood vessels and relieving pain. Therapists know exactly where the pressure points are and how to eliminate pins and needles in your left arm. They can also teach you how to perform acupressure on yourself.

2. Stretching

Occasional Numbness In Fingers

Stretching allows oxygen to flow throughout your body so no matter what is causing your tingling, it should help. When you perform stretching exercises with your shoulders, arms and core area, blood circulation improves to your hands, arms, legs and feet.

A good exercise to try begins with you standing with your feet lined up with your shoulders. Reach as high up as you can with your arms and then slowly lower them. Repeat but this time only use your right arm. Repeat again with only your left arm. Keep doing this sequence for about 15 minutes.

3. Rotational Exercises

Performing rotational exercises is a great way to get your blood flowing and increase oxygen to your extremities. If you are experiencing pins and needles in left arm, these moves might help.

Stretch your left arm out from your side. Make about 15 circular movements with your hand. Repeat the movements again but rotating in the opposite direction. Finish the exercises by flexing your shoulders, biceps and triceps, completing three sets of 15-20 repetitions.

When to Worry

Occasional Numbness In Big Toe

As mentioned before, occasional pins and needles is perfectly normal. These occurrences are typically temporary and will disappear own their own. Although commonly caused by too much pressure on the nerves, more serious conditions can cause the same aliment.

Occasional Numbness In Thumb

You should seek the advice of your doctor if the tingling feeling keeps returning. If the condition does not resolve itself, it may be a sign of a more serious condition. If any of the following accompanies the pins and needles sensation, seek immediate mediation attention:

Occasional Numbness In Toes

• Weakness, loss of consciousness, blurriness or confusion
• Tingling feelings begins after a neck, back or head injury
• Pins and needles start after a fall
• Loss of control of bowel movements or other body parts
• Movement of arm or walking makes tingling worse
• Dizziness, increased anxiety or generally feeling of uneasiness
• Increased urination
