Hi. Thanks for your query. Noted the history you have put in details about your symptoms, Endoscopy findings of inflammation from mouth to anus, ANA positive status, dismissed by Rheumatologist. I would think of the following since you have multiple lesions. - This definitely is a auto-immunity problem along with secondary problems due to malabsorption of many a things like multivitamins, minerals and trace elements. I would advise you the following: Get the additional tests for Vitamins including Vitamins A and D. Get all the deficiencies corrected by therapeutic dosages and see there will be a great difference as this will help to boost your immunity too. You may need oral steroids in tapering dosages and control of any other attendant medical problems like diabetes or so. Take a second opinion of another Doctor who can do a good clinical evaluation, examination and advise further investigations and and advise additional management.
