Fear is a lie, don't feed into it..
I've done a colonoscopy and it isn't that bad you won't die I have a seizure disorder and possible ICP intercranial pressure I survived came out of anesthesia having a seizure .
I pushed for a colonoscopy as I was having blood in stool,mucus ,and low ferritin levels and it's good I did they found a sessile serrated polyp and now I have to do a colonoscopy every 3 years.
Although the colonoscopy didnt pick up the sessile serrated polyp that was maligant in my appendix and I was lucky that planned surgery for something else included removal of appendix otherwise that cancer would of kept growing.
Do the colonoscopy it may save your life.
