I have skin tags and when I am in a flare they are swollen and hard and very painful. i also have a fissure that makes everything a hundred times worse.
I have had the skin tag since I was a teenager (it has seemed to split and turn into 3 tags now that are connected, has that happened to anyone?) and they thought it was a hemmoroid - I almost had it banded and removed - thank goodness I didn't, they strongly recommend against removal of perianal skin tags in Crohn's patients since the area does not heal well. Trust me, I would love to have it gone but am not willing to take that chance.
One thing that helped me immensely is getting a soft donut to sit on in my chair 9at home only or in the car, I am not at the point where I would ever take that out in public, lol) and also a soft squishy donut for the toilet seat - it REALLY makes a difference on how your weight is distributed and takes the pressure off your anal area.
