My husband is turning 40 this week. Last Friday morning he woke up with a horrible pain on his right side, underneath his ribs. The pain is so bad he s not sleeping, and even his normal prescription pain meds aren t touching it. We went to local ER today, and he was checked for kidney stones. Nothing showed in xray ct scan or urine test, except doc thought he saw particles in his bladder. My question is what could it be? A kidney stone wouldn t cause the whole back to hurting it was in th bladder, would it?
