My 16 year old step son is already going through a lot. He moved in because his mom is dying of breast cancer and can no longer care for him and now he has a kidney stone. He's been crying in pain and just wants it to end. He's in pain, throwing up, and running a fever. I've been trying to keep him hydrated and have just laid n his bed with him rubbing his back. I just want to help. Any remedies at all plz
