    A very common cause of shoulder pain is impingement. This is where there is a narrowing of the space between the acromioclavicular (ac) joint and the top of the joint which at that point is covered by the rotator cuff, specifically the supraspinatous ligament. This is often worse then the arm is brought up into adduction so the humerus is brought into contact with the ac joint.

    It can also be made worse by the development of bone spurs on the underside of the ac joint which may or may not be associated with arthritis.

    Treatments may include
    1. pain killers such as acetaminophen
    2. injections of Methylprednisolone, a synthetic form of corticosteroids
    3. arthroscopic acromioplasty
    4. an Inspace device which relieves the contact between the two surfaces
