Sit or stand and reach your sore arm out in front of you, with the elbow straight and the palm facing down. With your other hand, gently bend the sore hand down, so that the fingers point to the floor. You should feel a gentle stretch on the top of your forearm, not pain. Hold, then relax. Keep breathing normally.
If an exercise hurts more than you expect, stop and contact your clinician.
