If I have right knee osteoarthritis, do I have to work out my left side as well?
I was recently asked by a patient why he had to work out both sides of his body in physical therapy if only his right knee hurt. I can understand some of the confusion. After all, if your right shoulder were painful and inflamed and required an injection, the medication would only be put at the site of inflammation -- in your right shoulder. You would not be a candidate for a right and a left shoulder injection! However, physical therapy, for the most part, is much different. I'll explain.

Massage therapy targets this mechanism that causes muscle pain after physical exertion. There are many different types of massage therapy. The most popular style is Swedish massage. This soft, kneading style...
