Causes

The aetiology of carpal tunnel syndrome is unknown. It is thought to origin from one or a combination of the following causes and not from the nerve itself:

Genetic predisposition due to the narrower anatomy of the carpal tunnel

Excessive use of the hand and wrist in specific activities (maneuvering computer mouse and vibrating tools)

Injury to the wrist (fractures sprains) causing swelling of soft tissue

Age and hormonal changes as it is more common in older individuals and women

Underlying medical conditions such as Rheumatoid arthritis, diabetes and thyroid dysfunction (hypothyroidism)

Cyst formation in the carpal tunnel
