DM - Sorry you are hurting. I had bursitis when I was a teen. Dr gave me a shot of cortisone but it didn't help and I had trouble with that hip on and off ever since. In hindsight, that feeling is in my hip is the same feeling I get when the spasticity gets bad.
I may have missed something in your post, but is it a possible that the pain is being caused by spasticity? I find that when I get like that a nice warm (not hot) Epsom salt bath helps.
Sending you lots of cyber

's and hope you start feeling better soon.
Koala - Where did you get that picture of me? LOL
