What is tendonitis?
Even though tendons are tough, if you overuse them they can become sore and painful. This is called tendonitis.
Often called a stiff or “frozen shoulder,” adhesive capsulitis occurs in about 2% to 5% of the general population. It affects women more than men and typically occurs in people who are over the age of 45. Of the people who have had adhesive capsulitis in one shoulder, 20% to 30% will get it in the other shoulder.
Rotator cuff injury and inflammation is one of the most common causes of shoulder pain. There are three common conditions that can affect the rotator cuff: rotator cuff tendonitis, rotator cuff impingement syndrome and a rotator cuff tear. Most people with rotator cuff problems can be successfully treated by a combination of rest, painkillers, anti-inflammatories, physiotherapy and steroid injections. Surgery is sometimes an option.
Shoulder impingement syndrome is a common cause of shoulder pain. It occurs when there is impingement of tendons or bursa in the shoulder from bones of the shoulder. Overhead activity of the shoulder, especially repeated activity, is a risk factor for shoulder impingement syndrome. Examples include: painting, lifting, swimming, tennis, and other overhead sports. Other risk factors include bone and joint abnormalities.
What is shoulder instability?
Shoulder instability is a problem that occurs when the structures that surround the shoulder joint do not work to keep the ball tightly within its socket. If the joint is too loose, it may slide partially out of place, a condition called shoulder subluxation. If the joint comes completely out of place, this is called a shoulder dislocation. Patients with shoulder instability often complain of an uncomfortable sensation that their shoulder may be about to shift out of place–this is what physicians call “apprehension.”
Sprains and strains are among the most common injuries in sports. Here are some facts about sprains and strains from the American Academy of Orthopaedic Surgeons.
