Because the forearm (composed of the radius and ulna bones) spans from the elbow to the wrist, it is involved in a variety of everyday arm and hand movements. As a consequence, any injury or discomfort that affects the forearm also has the potential to disrupt daily activities ranging from typing on a keyboard to holding a cup. The forearm contains a host of muscles that can be rendered painful due to trauma that causes a fracture in the forearm bones and damage to ligaments and tendons; overuse during work or exercise that leads to “repetitive strain injury” (RSI); nerve entrapment; arthritis; or an underlying medical condition. Treatment varies in accordance with the cause of the pain and its severity.
