I'm on neurontin (sp?) for other nerve pain, but I found it doesn't really help me with the spasticity. I do hate that "almost" charlie horse feeling in my legs I get from time to time.
There are only a few things that have seemed to help it so far. The first is doing stretches when it's not hurting. The other is my new friend the heating pad. I sit for a few hours with it, switching it on and off so I don't get overheated.
I do know if it gets worse, I'll ask the doc for meds. Not sure if pain reliever or a muscle relaxer would work better for this.
Hope you feel better soon.
