Tennis elbow can be caused by a sudden or repetitive injury, often in people more likely to develop tendon problems. The treatment for acute injury is ice, rest, analgesics and stretching of the tendon. Chronic tendonitis is more difficult to treat. Ice or heat can be used, depending on what seems to help you most. Stretching the tendon is important. Massage, physiotherapy and acupuncture can be helpful. If the pain is severe, infiltration of cortisone is an option, but has side effects. Surgery can be helpful, but is not always curative.
Do these exercises at least twice a day
