Hello I was just wondering if anyone has angiodysplasia, went to the hospital for consultation after seeing blood after bowel movement and doctor examined me and said I have like birthmark's and the posh name for it is angiodysplasia. I'm having colonoscopy in 2 weeks to see how far up they go I'm so worried about the colonoscopy it's frightens me so much I hate machines & pulse things they put your finger in. blood pressure machine, just seeing that room puts me in a state of panic. Would be grateful to hear from anyone who has had the colonoscopy no horror stories please I don't think my heart can take it
