From your descript
ion, that sounds pretty bad now, especially since you require pain meds to control it. My doctor gave me pain meds for my attacks, but I didn't realize at the time that that type of pain medicine doesn't work on me at all. So I got to have all that pain and stuff without any meds to relieve it. Let me tell you, that makes "bad enough" happen pretty fast!
Your burning stomach, etc. could be the gall bladder. It can cause all sorts of weird things, including pain that shoots down into the right arm. I mean, who'd think that a gall bladder would make your shoulder and elbow ache? Been there, done that! It's actually a documented side effect too, so it's not that uncommon.
