Thanks to all for the feedback.
The leg pain was too much for me to soldier thru, so the dr called in an Rx for Fexeril. I took the lowest dose because I was nervous about side effects, and then went straight to bed. I believe the cause of the cramps was my recent alteration of Prednisone (from 20mg/day to 10mg)
I only took the Flexeril that one time, so I can't really give any feedback on its effectiveness, but I did sleep soundly thru the night and haven't had any serious cramping since.
Thank you all again for your input.
