My 27 year old son is passing a kidney stone. Not his first, that happened when he was 17 and we were told then that his body is constantly making them and this is going to happen to him often, which it has. My question: After the first few times, my son has not wanted to go to the hospital. He would rather just tough it out at home. Is there any point at which this is a mistake? He lives on his own so I don t always know when he is passing one. Today I stopped by though and he is miserable.
