Overusing the shoulder through repetitive lifting, swimming, gym workouts, painting, or other activities can place stress on the rotator cuff and surrounding tissues. This may contribute to tendon irritation and pain during arm movement. Shoulder impingement can also cause discomfort during overhead activity. Physiotherapy can help by addressing strength and mobility problems, improving shoulder mechanics, and gradually rebuilding tolerance to activity through targeted exercises and rehabilitation designed according to the individual’s symptoms and goals.
