The numbness, tingling and weakness are attributed to compression of the nerve. But through proper treatment, most find relief and restore function.
The condition usually comes on gradually. Those who suffer from it might first notice numbness and tingling in their fingers, as well as discomfort in the area, including the wrist, usually while performing a minor task like using a phone, holding a newspaper, or navigating a steering wheel. The infirmity may gradually move up the arm, becoming constant.
As the symptoms progress, the hand will become weaker, causing the afflicted to drop objects. This is because the median nerve can weaken the thumb and fingers, which are used to hold objects.
CAUSES OF CARPAL TUNNEL
Anything that compresses, irritates or crowds the median nerve can cause carpal tunnel syndrome. In many cases, it’s a combination of things, and no single factor can be pinpointed.
Some potential issues:
- Injury -- A wrist fracture sustained during high-impact activities or an accident can cause the tunnel to narrow from the swelling and inflammation attributed to the injury
- Rheumatoid arthritis -- A disease usually found in aging people, rheumatoid arthritis can cause swelling and inflammation in the carpel tunnel, impinging on the median nerve.
- Anatomical deformity -- Some people are born with smaller carpal tunnels, which makes them more susceptible to aggravating them with compression.
