So you may have IBS, too? I also have IBS and herpes. This isn't something I have had to think about, but it depends on whether there is nerve pathway from the spinal ganglion to the inside of the colon wall. I would guess no, but that's just a guess. Herpes has to travel the nerve pathway, so if the road doesn't go there, there's no way the virus can, either.
For extra security, you could make sure you're not having an OB when you go for the colonoscopy.
