Hi, I would like to know the causes of burning stool. like three days ago I started having a very severe burning stool and one thing that puzzles me is that I can eat and eat without going to toilet. Then if i eat heavy meal, after three hours I experience one of the most agonizing pain on my lower abdomen, then i have to remove everything from my stomach such that I feel very exhausted at the end of the process and nursing pain. I have pain in my right side of abdomen and i thought it could be appendix, went to the docs today did scan but they said there is nothing, I am frustrated, I am looking for positions to sleep, its really painful and i dread the time of passing stool. i dnt feel like eating I m eating just to stay alive. to be honest I m still suspecting appendix. please help.
