I would recommend seeing a gastrointerologist. If you haven't seen a specialist yet, it has been my experience that you need to advocate for testing outside of the norm in order to rule things out (i.e. MRI, Upper GI, etc.) After many tests we discovered my son is lactose intolerant and no longer experiences pain or vomitting on a daily basis. Our situations my not be related that way, but don't assume their opinions are fact. I would also recommend homeopathic measures over all of the medicines used to help with the reflux. Good luck to you.
