To make this short and sweet, my colon swelled twice the size of normal and ceased to function. It took my mom three days and a strong recommendation from my doctor (I could hear the /facepalm through the phone) to take me to the emergency room.
Spent 10 (count 'em, TEN) hours in the ER, most of it waiting. My doctor was pretty incompetent, and asked the same set of questions at least twice in one sitting. Then he hastily said I have colitis (three tests were done, none of which could determine if I had anything other than cancer or a bleeding ulcer), and the prescribed me a pain medication for the God awful pain I have from the swelling.
