I have noticed that when I use my PC keyboard I get sharp tingling pain in my middle three fingers. Why is that?

One of the most common nerve entrapment syndromes that affect thousands of people is carpal tunnel syndrome. Carpal tunnel syndrome has been increasing in incidence in the last 2 decades partly because of work related activities and our life style. The use of computers is one of the most common causes of carpal tunnel syndrome. The syndrome is caused by compression or irritation of the median nerve as it passes through the tunnel in the wrist. The nerve can be compressed or it may become irritated from repeated activities like typing, lifting, twisting, pushing or cutting maneuvers that involve the wrist.
