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.

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.
