Had a follow-up appointment with the colorectal surgeon for the results of the colonoscopy, and the results are that there is nothing wrong with me. No signs of any damage or disease (no crohn's disease, which is what they were concerned about).
And I don't have to have another colonoscopy unless/until I have further issues, but the surgeon is confident that the only issue I have is hemmoroids and those I get to treat by upping my fiber and water intake.
