overuse strain injury
     
         (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.
