relpax side effects

I just started taking relpax for migranes.  They have worked in releiving the headache pain, however, they cause me severe muscle/skin pain.  I hurt from head to toe.  It is my muscles and my skin that ache.  When I take the pill I know that I am going to experience this but at the time of the migrane it is a better alternative. Has any one else experienced this?
I currently take relpax as well, the side effects are similiar for me too. I take InnopranXL daily for migraine prevention as well. Relpax works great to rid the pain of the headache, but make you totally worthless.
Did you find anything that helped!? I am having the same side effect. Nothing else takes the migraine away though! I have tried Maxalt, Frova, naratriptan, they don't take the migraine away.
