"Oh, my back still hurts," Jim groaned as he sat on the bed and bent over to pick up his shoe. "Why don't you try a massage?" His wife asked. "My friend Carol swears massage is the only thing that can help her back pain." Jim sighed as he tied his shoe. "I suppose I have tried everything else. The chiropractor says my back is fine, just the muscles are tight. My doctor gave me muscle relaxants, which I don't like to take, and our insurance only covered four physical therapy visits. Massage can't hurt my back any more than it already does, I guess."
