How effective is shockwave therapy for calcific tendinitis?

Calcific tendinitis involves calcium deposits within a shoulder tendon. Shockwaves deliver mechanical energy to the painful area. The aim is to influence the local tendon environment and, when suitable, help the body deal with the deposit. Treatment may feel uncomfortable during delivery, and temporary soreness can follow.

Improvement is usually judged by easier reaching, dressing, sleeping, or lifting rather than by an image alone. A deposit may remain visible even when symptoms settle, while pain can persist if the shoulder is also stiff or weak. This is why the diagnosis, deposit location, symptom duration, and shoulder function all affect the likely response.

Ask a physiotherapist or doctor to confirm that the pain fits calcific tendinitis and that shockwave therapy is appropriate for you. The treatment plan may include activity modification, gentle range-of-motion work, and progressive shoulder strengthening. Avoid repeatedly provoking sharp pain while the tendon is irritable, but complete rest can also make stiffness worse.

Keep a simple record of pain during daily tasks and how far you can move the arm. Discuss the plan if symptoms do not begin to change over the expected review period, or if the shoulder becomes more restricted after treatment.

Seek prompt assessment for sudden loss of the ability to lift the arm, a new injury, marked swelling or redness, fever, unexplained weakness, or pain that is severe and rapidly worsening. These features may need a different assessment rather than another treatment session.

Could the deposit and tendon be confirmed with imaging? What improvement should we measure, and when will we review it? Which exercises should I do between sessions? What alternatives are available if shockwave therapy is not suitable or does not help?
