Hello my son is 2 and nearly every night he wakes up in pain, it occasionally happens when he is awake as well. It is worse when he is laying down or if we hold him when sitting. If we stand up he feels better. There is no timetable, it seems to be intermittent and ranges from mild to acute. He is not quite old enough to tell us what is going on. We have been to specialists and they don't know all tests have come back negative and now our pediatrician wants to give up until he can tell us whats wrong. I am hoping to find someone who may recognize these symptoms, some idea of where to look next.
