I am eighteen years old and i have already had 5 kidney stones. i have had two surgeriess to remove two kidney stones, out of the five i have only passed one. i had surgery about three weeks ago to remove one. and now i already feel like i have another in each kidney, i have had so many scans that the doctor doesnt like to do anymore for radiation purposes.. i am only eighteen! and i am getting really sick of it.. could i have some kind of illness or what? cause im pretty sure its not normal to constantly have kidney stones..
