My 13 year old son reported intermittent stomach churning for about two weeks, which my husband and I thought might just be indigestion. Then last week, he started retching at school. Initially he threw up a bit of green stuff (bile/stomach juices), but that was a week ago. Since then he has been off school and not thrown up at all. He has no nausea, no burning pain in the stomach, and no other symptoms like fever, illness etc. His skin colour is also normal (pink and white, not yellow). His main symptoms are frequent, unproductive retching and constant stomach churning. He also has some appetite, but not much. He has had no diarrhea and he can keep food down with no problem.
At first, we thought he had a simple tummy bug, but a few nights ago, the retching became very frequent and severe (like every few minutes). It stops when he sleeps though. The past few days, it didn't go away, but it is now about every 10 - 15 minutes. He is very uncomfortable with it, and can't really return to school like this. The GP is doing blood tests, but I was wondering about h pylori. The GP is more inclined to think it is some sort of tic, but I don't know that a tic would involve constant stomach churning and loss of appetite. There is the possibility of virus, but does anyone have any ideas here? I'm at my wits end and I admit to being very concerned by this, since I've never seen anything like it before.
Thanks very much in advance to anyone who has any ideas on this!! I'm really worried.
PS He has already had his appendix out, so at least we know it isn't that.
