What are the symptoms of rotator cuff tendinitis?

Pain is often felt over the outer shoulder and may increase with overhead work, putting on clothes, or reaching behind the back. The shoulder can feel sore after activity and may be uncomfortable when lying on that side. Some people notice weakness because pain limits effort, rather than because the muscle has suddenly lost function. Symptoms can build gradually after repeated use. Rotator cuff tendinitis and a tear can overlap in symptoms, while frozen shoulder is more associated with broad restriction of movement, so examination helps separate them.

Reduce or modify the activity that provokes pain without keeping the shoulder completely still. Gentle, comfortable movement can help prevent stiffness. A physiotherapist can assess shoulder mechanics and build exercise therapy around mobility, control, and progressive strengthening. A clinician may discuss medication or a cortisone injection when appropriate; shockwave therapy is another treatment that may be considered for selected persistent tendon problems. Do not use pain relief to push through sharp pain or repeated aggravation.

Book an assessment if pain continues despite activity changes, affects sleep, or limits dressing and reaching. Seek prompt care after a significant injury, or when sudden weakness means you cannot raise the arm. Get urgent help for shoulder pain with chest pressure, breathlessness, faintness, or sweating, because those symptoms may signal a problem outside the shoulder.

Ask which movements should be modified, how to distinguish tendon irritation from a tear, and when imaging is useful. Discuss the expected role of exercise therapy, the risks and benefits of an injection, and what improvement should look like during rehabilitation.
