I have no gall bladder, but about once a month I get a fever in my body, really hot in my hands and upper body, and I've never been food poisoned, as far as I know... But I link this with my symptoms, I chill and it feels like flu symptoms, but I can take any cold meds I have on hand, go to bed and eventually I get better, loss of appetite,not feeling like anything, lathergic, I'm 67, still working, my friends husband has pancreatic attacks and his diet has a lot to do with it so I'm told , I'm Probally 30-35 lbs overweight, still have terrible hot flashes, I take ice bags to bed with me at night! Thank you.... What does this sound like to you?
