overuse strain injury

medical (Or "repetitive strain injury", RSI, "repetitive

strain disorder") Any tendon or muscle injury resulting from

overuse, usually in the hand, wrist, or arm. Injury may be

caused by any combination of repetitive, unacustomed, or

prolonged movements, forcefulness, or an awkward position

(often due to bad ergonomics). The symptoms are pain,

tingling, weakness, numbness, swelling, cracking, stiffness,

or reduced coordination.

Common conditions are:

Carpal tunnel syndrome, where swelling of the membrane linings

in your wrist surrounding the tendons that bend your fingers

compresses the median nerve. This may result in numbness and

pain in the hand, arm, shoulder, and neck.

Tennis elbow, where rotating your wrist and using force causes

a form of epicondylitis.

Tendinitis, where unacustomed exercise or repeated awkward

movements inflame wrist, elbow, or shoulder tendons, often

leading to severe stiffness.

Trigger finger, a popping or catching sensation when you bend

your finger, wrist, or shoulder. This form of tenosynovitis

is caused by repetitive hand movements.

To prevent the condition worsening, treat the pain with heat,

cold, or aspirin, ibuprofen, or naproxen sodium; rest; or

immobilise the injured area with a splint or bandage. See a

doctor.
