Another opinion could be in order. There's nothing like a theraputic pool set at 100 degrees. I can walk in a pool w/o buckling or stumbling. I can actually walk aerobicly. Of course, that moist heat takes care of all of the achies for me regardless of their origin. I use self hypnosis when I have a surprise spike in pain and can't get to it with the meds in time. I also use it to help initiate sleep on bad nights. The visualization that I use is the therapy pool. I am practiced enough now that the sensation is almost as real as being there. The inflamation flows out of my body. The muscles turn to over cooked pasta. Life is good. Have a good night.
