I#39;d spent the September weekend playing two doubles tennis matches. When I went back to work on Monday, my left knee locked up and hurt when I got up from my desk. Walking down stairs brought on the same symptoms. The pain was mild and brief, but bothersome, nonetheless. I#39;d never had a sports injury in 35 years of playing tennis and had been proud of that fact.

The most common type of pain that I treat on a day-to-day basis is neck and back pain.

About 8.5 million people in Britain suffer with back pain caused by arthritis in the spine. Teri Honeyfield was virtually housebound until she had a new operation.

Eli Lilly Co. won approval to sell the antidepressant Cymbalta, its second-biggest drug, as a treatment for pain.

Slavishly following long-held guidelines for diagnosing the cause of arthritis-related back pain is resulting in excessive tests, delays in pain relief and wasteful spending of as much as $10,000 per patient, new Johns Hopkins-led research suggests.
