I too have ap·prox·i·mate·ly started around 10 at that point it was missed diagnosed til I was 15 and in er for over 12 hours because they couldn't figure out what was wrong first they thought bowel obstruction then finally my answer of kidney stone was discharged from we and sent over to clinic and waited in horrible pain and got to have my first surgery,of all time and was emergency because parents were in another city at work I was alone scariest part of my teen years and now I've been having them all time I am 34 now everything has caused me to have atrophic left kidney and currently in stage 3 chronic kidney disease since at least January 2019 so it's added new stress but trying to live life to it's fullest
