How wouldes typing and texting cause carpal tunnel syndrome?

Repetition: Repetitive flexion and extension of the wrist might produce a localized inflammation termed a synovitis, which can narrow the carpal tunnel beneath the transverse carpal ligament.

Probably do not: Most people that develop carpal tunnel syndrome do not have a clear cause. There is no science to show that it comes form overuse or typing. It is more likely in patients that suffer from diabetes or hypothyroidism or obesity. It is also more common in women than men. Flexing the wrist while typing may aggravate the problem by increasing the pressure in the wrist around the nerve.
