This may seem odd, but I think this may be a problem that I have. Well two things really, but they tie together. I work at a McDonald s restaurant, and when we have left over ice cream, I try not to let it go to waste. However, most recently, (because I have never had this problem in my life), after I eat it, I become very gaseous,(not in the mouth), and later when I get home, I normally have diarrhea . But now its not just with the ice cream at my store. Now it s regular ice cream you would buy in a grocery store too, plus frappes and other drinks that are similar to them. Am I lactose intolerant? Also, when I go to the bathroom lately, sometimes it is uncontrollable and it always smells like burning rubber. Most nights, I finish going, so I go back into my room and o on the computer, but within 10 minutes later, I have to go back, and this repeats for ,multiple times throughout the night. Also, If I eat something spicy, it burns really bad.
