My daughter was diagnosed with Kidney stones. She had severe stomach pains, and vomiting on and off for 2 weeks. After a xray they said she has 2 kidney stones, and they were in the lower part of one of her kidneys. We had her on pain meds for 2 days. Then stopped them. She still has some blood in her urine, when tested. Doctor thinks they must have passed. However she advised me there would be alot of pain when they move from the kidneys, which my daughter never had except before the xray that helped diagnose them. Could they have passed from the kidneys with no pain. I have heard sometimes they can sit dormant for while, then pass through. Just curious. We see the doctor for a follow up in a couple of weeks. Thanks for any info..
