I get these buggers and they are no fun.
The first one was the size of a adult thumbnail and they had to go up and get it. The pain was unbearable and I was in the hospital for a week. I had sweated so much because of the pain they had a IV in me for 3 days.
Good luck..stay away from soft drinks with caffine and drink lots of water.
I drink 2 pots of coffee per day, I think I am going to cut down now..
