I had kidney stones once. Thought my ex wife had poisoned me LOL. Passing them wasn't a problem for me, just everything up to that point. Never been in so much pain in all my life. I went from a lil discomfort in my lower back to laying on the floor puking my guts up in 30 minutes. Passed them about 4 hours later and was good to go. Dr. said it was cuz of red meat and beer. Hope you feel better soon
