To be honest I wonder if you had some traumatic injury to the celiac plexus. This sounds like a neuropathic pain secondary to the chiropractic manipulation. This is a very unusual story you give, so I can't say I have a strong hunch what is going on, but this seems like a reasonable thought. I'm sorry you've ended up in this predicament. You may consider seeing a pain specialist for discussion about a very particular procedure of a type of nerve block.
Thanks I added that to my list of things to look into and will be following up with someone on Monday to hopefully evaluate it. I have a list of everything that everyone on here has said and I'm going to bring it to the attention of the next doctor I find.
