Not a stupid question....I have perianal crohn's skin tags, the only time I had bleeding was from fissures on and around the skin tags...I've also hear that remi can shrink up perianal crohn's skin tags, and that cortifoam rectal meds can as well.
You should have your GI check out your anus to see if it's perianal crohn's skin tags/hemmies and then he should be able to give you treatment for it/them.
Here's a link that shows pics of both hemmies (first set of pics) and perianal crohn's skin tags aka; elephant ears (set of pics below the hemmie pictures...

Hemmies are completely different from perianal crohn's skin tags, but some people get anal tags from shrunken hemmies which is why it's best to see your GI.
