Really, complications from a colonoscopy are rare. I would not deter anyone from having one as it can most certainly save their life. I am very sorry this happened to you though. That's unfortunate. ARe you working with a physical therapist? I had horrible hemorrhoids when pregnant. I mean, like golf ball size. The hospital gave me a pretty great remedy that DID work. You use prep H when you go the bathroom, rub it on> Then next time you go to the bathroom you use a Tucks wipe (which I think you can use wipes dipped in witch hazel) and leave it in your underwear. Then prep H again the next time you go to the bathroom. It does a nice job clearing them up. Also, get your fiber, try not to strain. AND, this is an option for you which is the new colo guard tests. My doctor calls them 'poop in a box'. I have done it. Basically you get an envelop that has a liner for your toilet. You go number two and drop in the drops that are included. Pull out the liner, seal it and put into the provided lab mailing envelope and send it off. It's 95% accurate. The only downside is that if it is reactive, you then are to have the full colonoscopy to confirm. Insurance companies usually love it as it is so much cheaper than traditional colonscopies
But in general, this is an important test that has rare complications statistically.
