Well, if you are worried, perhaps you should get it checked out. There is no sense in stressing yourself out if you don’t have to. Stress isn’t good for your body either. I don’t think colonoscopy’s are horrible. I haven’t had to have one yet, but I think the lead up to it is probably the worst part and the actual procedure is not too bad. I have had several friends that have had them and while uncomfortable, it is worth knowing that everything is okay.
