Hi and welcome! This is a great place to get answers from lots of nice and informative people. I'll try to take a stab at some of your questions. The apthous ulcers are a part of Crohn's, and they can appear anywhere in the digestive tract including the mouth. The ones in your jejunum (small intenstine) are the result of Crohn's. Yes, they will get worse over time if you're not getting treatment- they get deeper and possibly more widespread, depending on how active your disease is. Are you on anti-inflammatories (i.e. sulfalazine, Pentasa, Asacol, etc)? Lessening the inflammation will help the ulcers heal.
Yes, unfortunately being very fatigued is part of the disease as well. Think of how tired you get when your body is fighting off a cold- it's the same thing, except your body is fighting off your digestive tract. Have you had your blood checked for anemia, iron deficiency, or vitamin B-12 deficiency? Those can make the fatigue worse.

You mentioned Tramadol and itching.............I would check with your physician on that drug. You might be allergic to Tramadol.
