Awwww KL.....I'm so sorry you're having those spasticity problems.

I can certainly empathize with you. The weather used to be a big factor in my case, but as the disease has progressed, any movement, anywhere, at all will send my legs, arms, back, etc., etc., etc., into crazy spasms. Of course I don't walk anymore, but those things are horrible....pain and more pain.
All I can offer is a big hug and to let you know you're not alone.
