I also have cramps however, it's unusual that one would get a cramp like a charlie horse under my chin like someone is poking their finger there as hard as they can. GOD>>>it's painful!
My husband thinks IM a nutt LOL...It really hurts. I took some potassium and it helped somewhat...I know that some seizure meds can play with the electralyte balance...
I found some good ways to prevent them...again thanx for your help here, I thought I was the only one who was crazy as the dr. cals it. WTH??
