The Institute of Quality in the Health Sector reported that tendinitis occurs mostly in the shoulder, elbow, knee and ankle, indicating that it attacks athletes and the elderly in particular.

The German Institute explained that tendinitis has several causes, such as repeated movement during exercise and the use of a long-time computer mouse and rheumatic diseases such as rheumatoid arthritis and osteoarthritis. Other causes include autoimmune diseases that attack tendon tissue, such as connective tissue disease, as well as diabetes, obesity, and smoking. Tendinitis can also be a side effect of some medications, such as antibiotics. Symptoms of tendinitis are severe pain when moving the affected organ, as well as swelling and limited movement. Tendonitis can be faced with rest and the use of splints or dressings while taking pain relievers. Massage, physiotherapy and ultrasound can also be used. In the event that the condition does not improve, resort to injections of cortisone or surgery.
