What are the treatment options for biceps tendinitis?

Biceps tendinitis causes pain where the biceps tendon runs through the front of the shoulder. Reaching overhead, lifting, or turning the arm may aggravate it. Treatment aims to calm the irritated tendon, maintain shoulder movement, and restore the strength and control needed for work, exercise, and daily tasks.

Physiotherapy may include posture work, shoulder-blade control, gentle range-of-motion exercises, and progressive strengthening of the rotator cuff and biceps. A cortisone injection may be discussed for selected persistent pain, but the injection site and diagnosis need careful consideration because the tendon can be vulnerable.

Reduce or modify the movements that reproduce sharp pain, especially repeated overhead lifting and heavy pulling. Keep the shoulder moving gently rather than holding it completely still, unless a clinician has advised otherwise. Use the exercise load prescribed by your physiotherapist and increase it gradually when symptoms settle.

Tell your clinician about a sudden snapping sensation, bruising, a visible change in the upper-arm shape, or a sudden loss of strength. These features may point to a tendon tear rather than irritation alone and can change the treatment plan.

Arrange assessment if pain persists despite modifying activity, interferes with sleep, or limits dressing and reaching. Seek prompt care after a fall or forceful lift if there is sudden weakness, bruising, deformity, numbness, or severe pain. Fever, marked redness, or a hot swollen shoulder also needs urgent medical review.

Ask whether the biceps tendon is the main pain source, whether imaging is useful, and which activities are safe. If an injection is suggested, ask about its purpose, location, alternatives, and how rehabilitation should be timed afterward.
