Many tests on the gall bladder, stomach, etc. Pain is extreme for a few hours after eating meat. It is still happening after 5 months. I mostly avoid meat. No other foods give me this problem. I also have developed low ferratin levels (8) when they should be 20. Docs cannot find where I am losing blood-did colonoscopy. Prior to all of this, I was bitten by a spider or tick or something on my hip and it still has not completely healed. Could all of this be related?
