Hi Moreta,
I know how bad the muscle cramps and soreness can be. Have you tried lidoderm (Lidocaine) patch? I know it sure does help with my muscle soreness! And if cost is an issue you could ask the pharmacy for ointment instead of the patches. It doesn't take all the pain away but takes the edge off at least. I used to take flexeril but it made me too tired so I was switched over to zanaflex and that seems to work out better for me. I hope you get to feeling better soon!
