What should you know about pain on back of forearm?

Pain that increases when you extend the wrist, straighten the fingers, grip, or lift may involve the extensor muscles and tendons. Repeated keyboard, tool, racquet, or lifting tasks can irritate these tissues. A fall or direct blow may cause bruising, a sprain, or a more significant injury. Burning pain, tingling, altered sensation, or weakness can point toward nerve irritation in the neck, elbow, or forearm.

Pain in the forearm is not explained by the forearm alone. Stiffness in the neck or shoulder, changes in elbow movement, and the exact location of tenderness can all help a clinician narrow the possibilities.

Temporarily reduce the movement that provokes symptoms, keep the wrist in a neutral position during tasks, and take regular breaks from repetitive gripping. A cold pack wrapped in cloth may ease recent soreness; gentle motion is preferable to forcing a painful stretch. Do not tightly strap the arm if it causes tingling or colour change. Seek assessment if pain persists, returns with ordinary use, or limits grip.

Get urgent care after a major injury, visible deformity, rapidly increasing swelling, inability to move the wrist or fingers, or new weakness or numbness. Prompt evaluation is also appropriate if the hand becomes unusually cold or pale, or if pain is severe and unexplained.

Ask whether the pain fits a tendon, muscle, joint, or nerve problem; which movements to pause; whether you need imaging; and how to modify work, sport, or computer use during recovery.
