tigerpawn...I have always been a mild case CDer, but I do have many tags. Do a search for post on skin tags. pb4 gives a great link to pics of the difference between hemmies and tags. Basically, my tags start as narrow at the base and are bulbous at the ends. They get worse/larger when I am flaring and many docs have told me that they are a great indicator for coming or current flares.
I have also had one fistula. The only way I knew what I had was leakage of fluid. I was lucky and had one in a limited muscle area so I did not have much pain. I just had more and more leakage of what turned out to be infected liquid. One visit to my GI and explaining the leakage--one look and he knew what it was right away.
Dx'd '90 (emergency rupture), symptoms ignored long before that, '03 fistulas and bad flagyl reactions, B12 weekly, Pentasa [until I surrender to the bigger meds]
I'm riding on the escalator of life....
