Why does my bum hurt?

I feel that it is imperative that you get in to see a "Gastroenterologist" They are specialists with the digestive system from mouth to bottom. You will need to stop eating all greasy, fatty, spicy foods for now to see if it helps.This is not just a simple thing that you can ignore. This is actually something that can be quiet serious.For the diarrhea take Imodium and for the indigestion try and take "Gas X" I like to recommend the chewables. Now they are kind of strange because they can make you h at the mouth depending on how bad the acid levels in your system are at the time.Feels almost kind of funny. :) I hope that you set up an appointment fast this is not something to ignore. Please keep me updated I will be concerned for you.
