I have issues with my perianal crohn's skin tags, I was tole they were hemmies (the skin tags is how my CD started, not in the TI like most) anyways, they banded the tags while the tags were in a flare, BAD IDEA TO DO ANYTHING WITH TAGS DURING FLARE (when the tags are enlarged and hard is when they are considered to be in a flare...apparently getting them snipped off when not flaring is fine but does not guarantee that new ones won't re-appear cuz they most often do.
Gettng anything done (especially cut off) while flaring often leads to infection and a continuous wound (won't heal) so it's not worth the risk...Mine were banded while flaring (large and hard) so have remained that way ever since (before the banding they used to just come and shrink back down on their own, which is why no one had any clue that CD was basically "developing" for me.
Check out this link, the first set of pics are of actually hemmies, the pics below that are of actual perianal crohn's skin tags (aka; elephant ears)
