I need to have a scope. They say I need to have a colonoscopy & an endo. but I think that most of my problems are in my upperGI region & or esophagus. SInce it starts taking pix in your mouth, would it not be easier to use this for mouth to smaller portion...? I will not have anything you have to use anesthesia, narcotics, or whatever with. I have had several severe reactions & do not want to die... it kind of defeats me trying to save my life with these other tests! I dont mind pain, so I would consider the sigmoidoscopy/ whatever & the PILL... I understand its not as guaranteed as the other but having nothing at all is of no benefit to me either!
