My son is 9 years old Nd woke this morning saying his stomach hurt.  It continues to hurt with any laughing, coughing, jumping, bending etc.  no loss of appetite, fever or n/v.  He had a bowel movement last night.  Pain with palpation, somewhat generalized even up to ribs, both sides.  Any concerns?  Tylenol does not help.
