Carpal tunnel syndrome (CTS) is one of the most common entrapment neuropathies, and is caused by compression of the median nerve

The median nerve supplies the muscles in the flexor compartment, and provides sensory supply to the thumb, index and middle finger

Carpal tunnel syndrome mostly has an idiopathic etiology, that is, the cause may be unknown

Occupation-related factors like typing or anything that involves repetitive wrist use may lead to this condition

Medical conditions like diabetes mellitus may cause nerve changes, which may increase the risk for carpal tunnel syndrome

A reduction in the normal levels of the thyroid hormone, known as hypothyroidism, can also be a risk factor

Trauma to the distal part of the radius (one of the two bones in the forearm) may cause fracture. If not treated adequately, it may cause malunion, further leading to CTS

Symptoms like tingling and numbness in the thumb, middle and index finger may be experienced by the affected person

Nerve conduction studies could help in diagnosis, and some pain-relieving medications may be advised by the healthcare provider
