My hand went into a cramp and my fingers curled and my hand curled closed. When it finally relaxed and I was able to open it I had a raised knot under my little finger and ring finger. About 2 minutes later the cramp completely released and the raised area gone. Then it hit again, this time I pulled off on the side of the road afraid I was having a stroke. Dont know why that was just the first thing that came into my mind. I have cramps in my legs and feet all the time. I take 3 potassium pills everynight before I go to bed to keep from having them.
