Muscle swelling is the cause of bad posture. It is an injury that occurs when you are slouching instead of sitting up straight, or your wrists bend. Most injuries while typing occur if you are sitting and working at a computer for a long period of time. After you use your fingers a lot like when you are typing, most likely you develop tendonitis which causes the swelling.
How To Prevent
To prevent this try not to adjust your chair so that it is in a reclining position, also try adjusting the angle of your keyboard. The chair should be adjustable so you can set its height. The position of your typing keyboard should require your elbows to bend at a 90 degree angle allowing your arms to remain at your side and allowing your wrists to remain in an almost straight position.
Carpal Tunnel Syndrome
Carpal tunnel syndrome occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes squeezed at the wrist. The median nerve controls sensations to the thumb and fingers, as well as impulses to some small muscles in the hand that allow the fingers and thumb to move. Carpal tunnel syndrome is the most common and widely known syndrome while typing. Pain usually start gradually, with frequent burning, tingling, or itching numbness in the palm of the hand and the fingers, especially the thumb and the index finger. Some sufferers say their fingers feel useless and swollen when it occurs.
