I found an excellent article on shoulder problems: Evaluation of the Patient with Shoulder Complaints Bruce C Anderson, MD, Clinical Associate Professor of Medicine, Oregon Health Sciences University, Portland; Ronald J Anderson, MD, Associate Professor of Medicine, Harvard Medical School. "Shoulder pain is a common musculoskeletal complaint that may be due to either intrinsic disorders of the shoulder or referred pain. The former include injuries and acute or chronic inflammation of the shoulder joint, tendons, surrounding ligaments, or periarticular structures. This review will provide a general approach to the evaluation of patients with shoulder pain." http://www.medscape.com/UpToDate/2000/12.00/utd1201.11.ande/pnt-utd1201.11.ande.html or NOTE: To view the article with Web enhancements, go to: http://www.medscape.com/UpToDate/2000/12.00/utd1201.11.ande/utd1201.11.ande-01.html You do have to sign onto the site to read the articles, but it's free and easy to do and well worth the effort.
