I have had 4 back surgeries, one on my neck and three on my low back. Recently my low back muscles have become swollen and I can not use ice on them because I have fibromylgia and ice sends me into major muscle spasms. Is there any other treatment to reduce the swelling? I am on muscle relaxors to help with the muscle spasms. I just have not been able to get the swelling to go down. I was just wondering. Thank you.
