Carpal tunnel refers to a passageway that is located at the base of the palm, where the hand meets the wrist. This tunnel is bound by ligaments and bones, and it provides protection for the median nerve that runs to the hand and nine tendons that facilitate the bending of fingers. When the median nerve is squeezed or pressed at the wrist, numbness or pain may result. Regular pressure on the nerve may cause the hand to become weaker, and this is the most prominent sign of carpal tunnel syndrome.

Common Causes of Carpal Tunnel Syndrome

Carpal tunnel syndrome is usually caused by the application of pressure on the median nerve or the tendons that are found in carpal tunnel, and it does not result from a malfunction of the nerve. The size of the carpal tunnel varies from one person to another, and those who have smaller and narrower carpal tunnels are more susceptible to the syndrome. Certain health problems can also increase the risk of carpal tunnel syndrome, and these include rheumatoid arthritis, thyroid disorders, and diabetes. Other biological conditions that are linked to the syndrome are menopause, pregnancy-related fluid retention, amyloid deposits, an abnormal protein that is produced by bone marrow cells, and tumor or cyst in the tunnel.

Carpal tunnel syndrome can also occur because of injuries that cause swelling in the wrist, such as fracture and sprain, as well as work stress and frequent use of vibrating hand devices. Although many people believe that repeated movements of the wrist and hand can lead to carpal tunnel syndrome, there is not enough clinical data available to prove that this is true. Repetitive motions of wrist and hand can result in tendonitis and bursitis, but these are not symptoms of carpal tunnel syndrome.

Symptoms of Carpal Tunnel Syndrome

The symptoms of carpal tunnel syndrome develop at a slow rate. People with the condition frequently experience burning and tingling sensations or itching and numbness in their palms and fingers. Some of them may also feel that their fingers are swollen and useless, even though the swelling is not visible. Usually, those who are suffering from the syndrome may have to “shake out” their wrists and hands when they wake up in the morning.

As the symptoms of carpal tunnel syndrome become worse, the tingling sensation may be felt during the day. Later on, grip strength will be significantly reduced, making it difficult for sufferers to grasp smaller objects, form a fist, or perform certain manual tasks. If the condition is left untreated, it may cause the muscles below the thumb to lose function. Certain people with severe carpal tunnel syndrome are unable to feel the difference between hot and cold with their hands.

Home Exercises for Management of Carpal Tunnel Syndrome

One of the most effective ways to manage carpal tunnel syndrome is to perform hand and wrist exercises. These exercises are very easy to do, and they can be performed at home or in the workplace. The first exercise is the prayer stretch exercise. To do this exercise, stand up and place the palms together close to the chest. Then, slowly lower the hands down to the stomach and hold them there for 15 to 30 seconds. Another popular exercise is the wrist flexor stretch. This exercise can be performed while sitting or standing. With arms stretched out in front, bend the wrists up and down. When performing stretch exercises, carpal tunnel syndrome sufferers should not stretch their wrists to the extent that they feel pain or discomfort. Overstretching can cause inflammation, which can in turn worsen the condition.

Those who are experiencing any of the symptoms of carpal tunnel syndrome that are mentioned above should consult a doctor immediately. If the condition is not treated promptly, it may eventually lead to a physical disability.
