This worked wonders for me. But....BUT...my patch came off and of course with heat you have to be careful and limit the time in hot water. It helped with movement in my arms and hands and eased pains when i used then under water. The physical therapy dept. allowed me to use their pool for $3.00 a day but I had to quit because they had too many others who needed the pool and my insurance only covered so many visits. The solution, join a healthclub...talk about expensive pools. So for now I wait. If you can use it, try....it can't hurt.
