What leads to carpal tunnel syndrome?

Nerve compression: Carpal tunnel syndrome is median nerve compression in the carpal tunnel at the base of the palm. Increased pressure in the confined space of the carpal tunnel causes compression of the nerve resulting in numbness of the thumb, index, long, and half the ring finger.Common causes are underlying tendonitis, overuse and repetitive use, pregnancy, and diabetes or hypothyroidism are predisposing factors.

Genetics clearly plays a major role too and having a first degree relative with CTS is a major risk factor for getting it. Over-use and repetitive use are over-rated as causes. There probably is a mildly increase risk if your job involves 10 hours a day of heavy and continuous use of vibrating tools or immensely repetitive strenuous grip (14 hour sheep shearing shifts are a good example I think)
