When I overdid myself last week and had a cascade of events to follow this was one thing I was getting really bad cramps ? And then the next day I was soooo sore....my drs were tying to say it was my meds maybe to strong, but I knew it was a different kind of cramp. Two emergency rooms later, and 2nd day in the hospital. Can barely walk...neuro said she thinks it was antibioti cs my other dr put me on or my menstration. Something hit my body n it just gave in even tho I was doing good on pred n mestinon prior.
Listen to your body and call ur dr if it doesn't go away mine just got worse.
Good luck!
