I put this on the back forum earlier, but no answers as yet, and with the twitching that everybody has been speaking of here, I thought I would ask you all about it. I have Degenerative disk disease in my back and have been having terrible problems with weakness and pain in my extremities. On top of this, I have FM, with lots of new things going on lately. I had a full spinal MRI yesterday and it took about 1 1/2 hours to complete. They did let me have a couple of 2 or 3 minute breaks during that time. I have had several MRI's in the past, but have never had this happen to me. My fingers began twitching and jumping similar to eye twitching. As time went on the muscles in the tops of my thighs also began doing this. It wasn't like flopping around jumping, but I couldn't control it at all. I get occasional spasms like this, but they only last a few minutes. This time it was pretty much during the whole scan. They were going down my arms and even the tops of my feet. It's hard to hold still when that's going on. The tech said it might have been from lying there in the 1 position so long. Anyone els have this happen? Thanks for your input.
