Carpal tunnel syndrome

Carpal tunnel syndrome is a common condition that can cause pain, tingling, and numbness in the arm, wrist, hands and/or fingers. It is caused when the carpel tunnel opening in the wrist, which the median nerve travels through, becomes smaller and pressure is exerted on the nerve. Swelling/inflammation is the most common reason the carpal tunnel narrows. It can occur as a result of injury, pregnancy, or chronic illness, such as, hypothyroidism, obesity, rheumatoid arthritis, and diabetes.

It can also occur as a symptom of ME/CFS.
