I had a big one about 12 years ago. it was the size of a nickle. Hurts like a mofo. Had 2 failed attempts at lithotripsy, then up the old wanger they went. Broke it up with an ultrasonic probe. I pissed gravel for a week. Drink plenty of fluids. My doc said he didn't care if it was water or beer. I drank beer.
. Good luck!
