It is the muscles that spasm, but MyMSBS is right, it can cause inflammation to the surrounding tendons/tissue/etc..

Stretching and using the muscles does help, even though it is hard to do when you hurt and are fatigued. I've had good success with aqua therapy over the past year, and my therapist also does something called "trigger=pointing" where she presses on the spastic muscle to get it to release. It hurts very badly at first, but then you can feel it give way and the relief that comes with that. I would suggest a good Physical Therapist if you don't have one, they can help a lot.

I guess exersize is the right answer. I know it's hard to keep it up with our extreem pain.I just kave to tell myself to continue. Good luck honey!!

Most of us suffer spasticity in the legs at times. This week has been horrible for me, including fatigue and pain. I live in Hawaii and this past week the humidity level went up more than usual. Consequently I'm theorizing that the humidity level in general can exacerbate spasticity. Hope this helps.

I have been suffering from this for three months really bad. I know what you are going through. I got my best info off of webmd.com. The spastic muscle can try to wrap or tighten around tendons or joints. No wonder it is so painful. Many a night I have jumped out of bed from this pain. I've tried Zanaflex, Baclofen, and other drugs I can't remember right now and they make me extremely dizzy. Right now I'm on 2mg of valium 3 times a day which has helped better than anything else, but I think I need a stronger dose. I read about a Baclofen pump that can be implanted to deliver it right into the spine and bypass most of the drug symptoms. I think I may look into this. Causing inflammation, per MyMsBs, is a new thought to me. My Neuro also recommended water exercise like rachbach said. I really hope you do get to feeling better.
