What should you know about severe pain in left forearm?

Forearm pain can involve muscles, tendons, bones, joints, or nerves. Repeated gripping and wrist movement may irritate tendons near the elbow. Golfer's elbow commonly affects the inner elbow and forearm, whereas tennis elbow is usually felt on the outer elbow and forearm. A blow, twist, or fall may cause a sprain or fracture. Burning, tingling, or altered sensation can point toward nerve irritation. The left side matters because pain in the arm can sometimes accompany a heart problem; the pattern and associated symptoms are more useful than location alone.

Pause lifting, gripping, and repetitive wrist work. Keep the arm supported in a comfortable position and use a wrapped cold pack after a recent injury if it helps. Remove rings or tight items if swelling is developing. Use medication only if it is safe for you and follow the label or your clinician’s instructions. Arrange an examination if pain remains severe, movement is restricted, or symptoms do not settle. Assessment may include checking strength, sensation, circulation, elbow and wrist movement, and the injury mechanism.

Call emergency services for forearm pain with chest pressure, shortness of breath, sweating, nausea, or pain spreading to the jaw or back. Seek urgent care after a significant injury, for a deformity, rapidly increasing swelling, a cold or pale hand, severe pain with a tight swollen forearm, or new weakness or numbness. These signs can require immediate treatment.

Ask whether the pain fits a tendon, bone, muscle, or nerve problem; whether you need imaging; which movements to avoid; and how to return safely to work, exercise, or physiotherapy.
