I have Crohn’s disease and have had an anal skin tag for a while. It’s large, it’s ugly and makes me feel so insecure. So I decided to band it. It started going kinda black but today it’s yellow.... now I’m wondering if it’s infected? There’s no pain at all. Just the change in colour has me wondering. Has anyone ever banded or tied off skin tags and tell me what the colour change should be like?
