Hello! I'm new to the forum as well. Your symptoms sound a lot like mine now & pre-diagnosis. When I have horrid mouth ulcers I know that all heck is about
to break loose in my intestines as well as intestines. My advice to you would be to find a really good Gasroenterologist first and get he/she to perform an Upper endoscopy, colonoscopy & Barium X-ray. Since finances is a issue the colonoscopy, in my opinion, should be at the top of your list of procedures to get done.
Until you see the GI I would reccomend just taking it easy, staying hydrated and not stressing out. Stress makes any medical condition worse. If you are having continuous bloody bowel movements I would take a trip to the ER.
