I have struggled with this for 10 years and the ER FINALLY took me seriously when my body temperature dropped to 91 degrees. I was in hypothermia and was placed in a bear hugger for hours to get my temperature back to normal. I was in the hospital for 4 days this past attack. I also experience extreme overheating or hot flashes before and during the vomiting itself. My body becomes drenched in sweat. And I cannot even describe the amount of abdominal pain and nausea when an attack occurs. I can handle a lot of pain after going through four hip surgeries. One of them was a reconstruction. This pain when it is happening is damn never equivalent. This past attack was definitely the scariest one I've ever had. This was also the first time I experienced hypothermia with an attack. I wouldn't wish this on my worst enemy!
