Why is my thumb going numb?

Answer

According to Massachusetts General Hospital, pressure on the radial nerve of the wrist or forearm can lead to thumb numbness. Compression of the median nerve located in the palm between the pointer and middle fingers can also cause numbness in the thumb. Additionally, the nerves of the forearm are based at the neck, leading to numbness of the arm and hand if the nerves are compressed.

Medline Plus explains that carpal tunnel syndrome is a condition in which the median nerve is compromised due to constant pressure, leading to pain, numbness and tingling in the wrist, palm, thumb and index finger. Carpal tunnel syndrome is caused by repetitive motion of the wrist and is common in individuals who type on a daily basis or play frequent sports.

According to the Arthritis Foundation, numbness in the thumb and fingers is a classic symptom of carpal tunnel syndrome. Additional symptoms include burning, tingling and pain in the hand. Individuals with long-standing arthritis are at risk for bone spurs that can lead to compression of the median nerve, in turn causing numbness and tingling of the thumb and fingers. Carpal tunnel syndrome is treated with night-time wrist braces and steroid injections. In severe cases of carpal tunnel syndrome, surgery is often required in order to release trapped nerves.

You could have a trapped nerve. A massage could help that. Get someone to rub your neck for you, or you could try it yourself. Also try a heat pad over the back of your neck.
