To manage pain, your doctor may recommend:
Compression can help prevent more swelling. Your doctor may recommend an elastic compression bandage around your forearm. Be careful not to wrap the bandage too tight.

When the acute pain is gone, start gentle stretching as recommended. Stay within pain limits. Hold each stretch for about 10 seconds and repeat six times. Stretch several times a day.
