Had horrible lower back pain and threw up a couple times. This was in the middle of the night. I just buckled over, went to bed and went back to sleep. Then work. My back still hurt a little, but now my left side hurt a lot. I went to the Doctor. Said I had blood in urine and that I had a kidney stone & should drink tons of water. It has been a week. Off & on back pain with same left side pain. Now I'm having burning in abdoman and feels like I keep having to urinate. My back hurts again. Is this how you feel before the actual stones pass? PLEASE HELP. Thanks.
