My 9 year old son had 3 kidney stones in October and he spent a agonizing week in the hospital while they tried to find some pain meds that would even begin to reduce his pain. Truly the worst pain I have ever seen him in and my son has an abnormally high threshold for pain.After that experience we thought all was fine, but when we went for a follow-up ultrasound last week to just verify they were all gone we found out he has one again. Not sure if it's one of the October ones or a new one.Anyhow, my question for those who have had kidney stones is - can this just exist in his kidneys forever and ever without it causing problems or is it destined to come out? I feel like the other shoe is going to drop at any minute and would love to hear from someone who has had one for a couple years and it never caused a problem because I don't know if I can stand seeing him in that amount of pain again.
