Overuse injuries can result from repetitive athletic movements (running, swimming, weightlifting, golfing), repetitive occupational demands, poor posture, or unresolved past injuries. Chronic soft-tissue stress (micro-trauma) can cause your body to produce tough, dense, scar tissue that alters normal movement patterns and joint function. Injuries can manifest as a loss of strength, pain, and decreased range of motion. If a nerve becomes entrapped numbness, weakness, and tingling can result.
