What does pain when lifting the arm feel like with rotator cuff tendinitis?

Rotator cuff tendinitis often causes a sore or burning feeling around the outer shoulder, sometimes extending into the upper arm. Lifting sideways or forward, reaching overhead, fastening clothing, or reaching behind the back may produce a painful catch. The discomfort may increase through repeated use and ease when the arm rests. Night pain can occur when lying on the sore shoulder. Stiffness or reduced confidence in the arm may accompany the pain, but marked sudden weakness deserves a separate assessment.

The tendon can become irritated after repeated overhead activity, a change in exercise, or sustained shoulder loading. Similar symptoms can arise from other shoulder or neck conditions, so the sensation does not identify one diagnosis by itself.

Temporarily scale back painful overhead work and repetitive reaching rather than keeping the shoulder completely still. Use comfortable movement to prevent stiffness, and change sleeping position or support the arm if night pain is troublesome. A physiotherapist can tailor exercises that gradually restore shoulder control and strength. A medical professional can advise on pain relief and review progress if symptoms do not settle.

Book an assessment when pain continues to restrict work, sport, dressing, or sleep, or when the shoulder is becoming less mobile. Seek urgent care after a significant injury, or for a shoulder that is visibly deformed, an arm that is numb or cold, or sudden inability to lift it. Chest pressure or breathlessness alongside shoulder pain requires emergency help.

Which movements are aggravating the tendon? What level of exercise is appropriate? How will we distinguish tendinitis from a tear, neck pain, or joint stiffness?
