Biceps tendons connect the biceps muscle to the bones at the shoulder and elbow. These tendons can fray from heavy use over time and then completely rupture or tear from injury, such as from lifting a heavy object. Or one may rupture from repetitive activity such as swimming or tennis.
Symptoms include:
- A pop or snapping at the time of injury.
- Sudden, sharp pain in the shoulder or elbow.
- Swelling, bruising, and tenderness.
- Weakness.
- Bulging in the upper arm.
- Trouble turning the hand palm up or palm down.
For many people, the pain from a partial tear in the tendon resolves on its own over time. Treatment may involve:
- Rest. Stay away from heavy lifting or overhead movements. Your doctor may advise using a sling for a brief time.
- Ice. Use an ice pack for 20 minutes several times a day. Wrap the cold pack in a thin towel to protect your skin.
- Physical therapy. You may go to a physical therapist, or your doctor may instruct you to do certain exercises at home.
If these measures don't allow you to heal, surgery to reattach the torn tendon may be recommended. This may be important for athletes or people who need arm strength to perform their job. Surgery is almost always required for a fully detached biceps tendon. After surgery, rehabilitation is needed.
