Staying in shape and staying active are useful practices for a variety of reasons. Osteoarthritis is the most common form of arthritis in the U.S. right now and simply staying in shape and active are 100% effective means to treat joint pain created by this condition.
I work for a marketing company that is working with the Arthritis Foundation and the Ad council to make people with Osteoarthritis more aware that staying active is the best way to prevent/treat OA associated joint pain. Moving is the best medicine!
