I had two kidney stones and believe me they were very painful. I was on active duty in the Army at the time and after the stone was verified the Military Doc at Sick Call, said to go home and drink plenty of fluids. He said if you like beer, usually two six packs will do the trick. Beer serves two purposes: One, it gives you plenty of fluid and two, it helps with pain management. I took the doc's advice and sure enough, after 9 beers, the stone passed.
A doctor told my dad essentially the same thing.
He used to suffer from them.
I’ve had three or four that I can remember.
