Hi coplover:

One can only speak from personal experience. My spasticity started with pain in my groin area. My leg was stiff. Sometimes weakness made me fall even though the pain was still there. Finding a balance between treating the pain and stiffness and walking can be tricky.

Here is a good link to what spasticity feels like:

If you google spasticity you will get some helpful links.

Calf pain can be caused by exercise-related problems. Your doctor or physiotherapist might be the best one to help you with that.

Good luck - hope it resolves soon.
