My Ex-boyfriend, but still great friend is very sick and has been for the past year or two. When he gets sick he has SEVERE abdominal pain and is extremely nauseas, those are the first signs. The nausea turns into uncontrollable vomiting, usually bile that doesn't seem to stop. Then he SWEATS profusely, so much to the point where we will have to change his hospital bedding (including the big gauze pad or whatever it is) and his clothing every 20 minutes or so. Alot of the times he has no fever though. He says that he feels cold (4 warm hospital blankets aren't even enough at times), and his stomach pain is unbearable. I hate to see this man go through this, its tearing him up. This is much more than the flu or common cold. The hospital emergency room visits happen atleast once a month and its so saddening. He cannot eat when he gets sick, and he can be sick for days. He's been losing weight like crazy over this. If anyone, ANYONE, has any type of idea or similar issue please post. I need your help, I can't stand to see him in pain. We've seen GI "Specialists", Doctors just about everywhere, absolutely nothing has helped. They can see how sick he is, but frustratingly they tell us they cannot find anything wrong with him. Those symptoms listed above are the only symptoms, he was just released from the hospital yet again today and this is getting to be pretty nerve-wrecking. Any help, or guidance in a direction as to what to ask or suggest to the next doctor would be greatly appreciated.
