question: hi there. 8 years ago i had a liver transplant operation. my health has been on and off ever since. for the past year and a half, ive been experiencing horrible gut pains. ended up in hospital for months at a time. which no final cure. i now weight only 86 pounds. i am 64 years old. after eating my body gets really hot flashes, followed by tightening of my stomach , especailly on my right side. pain leaves me curled in a ball. find myself rubbing these extremley hard spots on my stomch, trying to soften them up.if i go to washroom there is alot of gas/ strong air that rushes out. what could this be?
