Understanding Biceps Tendonitis (Distal)

Front view of upper arm showing biceps muscle.The biceps is the muscle on the front of the upper arm. Biceps tendons are connective tissue that attaches this muscle to the bones of the shoulder and arm. Overuse or a sudden injury to tendons can cause pain. When this problem occurs at the inner elbow, it is known as distal biceps tendonitis. Distal refers to the elbow end of the biceps, because it is farther away from center of the body.

Causes of biceps tendonitis

The biceps tendons can be damaged by:

  • Lifting too heavy a weight

  • Using your arms more than usual, such as training harder for a sport or doing a task that requires a lot of lifting

  • Low-level stress on the tendons over time, especially repetitive motions

  • Other injuries to the arm or elbow

Symptoms of biceps tendonitis

These may include:

  • Pain or tenderness at the front of the elbow

  • Pain that gets worse when bending the elbow or rotating the forearm

  • Arm weakness

  • A crackling sound or grating feeling when moving the elbow

Treatment for biceps tendonitis

This problem often gets better with rest and medicines. Treatments aim to reduce pain and help the tendon heal. Possible treatments include:

  • Avoiding actions that make the pain worse to allow the elbow to rest

  • Using over-the-counter or prescription pain medicine to help relieve pain and swelling

  • Applying cold packs to help relieve pain and swelling

  • Trying stretches and other exercises to help with range of motion and strength

If these treatments don’t do enough to relieve symptoms, physical therapy may be helpful. For severe symptoms, or if the tendon ruptures, your healthcare provider may advise surgery to repair the tendon.  


When to call your healthcare provider

Call your healthcare provider right away if you have any of these:

  • Fever of 100.4°F (38°C) or higher, or as directed

  • Symptoms that don’t get better, or get worse

  • New symptoms

  • Bruising or swelling of the injured arm

  • Bulging appearance to the biceps muscle on the injured arm
