Is shoulder pain always frozen shoulder? Shoulder pain is a common clinical symptom. Before patients come to the hospital, most of them are diagnosed as “frozen shoulder” outside the hospital. After detailed physical and imaging examinations, fortunately, less than 20% of these patients actually have frozen shoulder. That’s right, less than 20%. What kind of shoulder pain do these patients have? Usually, shoulder pain is caused by “rotator cuff injury”, “biceps tendonitis”, etc. caused by a violent activity (e.g., walking, pulling a hoop when riding a bus, pulling a car in a hurry, etc.), or by repeatedly lifting the upper arm outward. or “shoulder impingement syndrome” caused by repeatedly lifting the upper arm outward. What exercises should a patient with shoulder pain do? We know that when you have frozen shoulder, you need to exercise to promote the release of adhesions, but, but, but – and this is important to say 3 times – if you have a rotator cuff injury, or a biceps tendon injury, you need to exercise. If these patients have to exercise, or even strengthen their exercise, then unfortunately, you will never get better.
