I don't want to scare you but if you are new to all this, it is common to go back and forth with diarrhea and pain unless you can find a medication which works for you, UC or Crohn's. Many of us have tried many medications/combos and still have trouble. This is something you are going to be dealing with now regardless of if it is Crohn's or UC. I would tell the doctor at your next appointment you were told UC and then Crohns and see what they say. Have you changed your diet and are you taking any rectal medications?
