Have Tubular Adenoma. I had undergone a Flexible Sigmoidoscopy and the doc found one of these and removed it.Now I have to go back to the clinic and have a full Colonoscopy done. I had some rectal bleeding and pain bad enough to prescribe me Vicodin to take for it. I am 37 years old,I also have Atrial Fibrillation and major depression disorder. I am like what else can go bad in me??? I am starting to feel like a old broken down car. I get easily fatigued and have frequent lightheadeness to and usually chest discomfort. Are there any others out there that have been thru this stuff??
