Every since I had my first child I have had rolling back spasms. It starts at the base of my spine and the pain and cramp rolls up my back to the neck. Some are so strong they actually pull my head back. The are so painful and control the muscles in the back that all activity that I was doing stops. I have not fell from it. I have difficult talking because I'm useally moaning from the pain. The doctors have no clue. The last thing that was said about 6 years ago it was from having children and it would go away. It hasn't. I can be sitting get up to move to another chair and there it goes. I could walk in from driving and have one while I'm trying to walk. There is no rhyme or reason for the attacks. Nothing makes it worse or better. 6 years ago I was diagnosed with FM. The attackes last less than a minute.
