More in line with the Gross Out thread, I'm also allergic to adhesive tape, which is also related to the latex allergy.
If you put a band-aid on me anywhere but my fingers and heels, within 15 minutes, I'll have this red, prickly rash when you pull the tape off. I had mole removed from my neck that was melanoma. So the incision was quite long to help hide it in the crease along my jaw line. I had a lot of stitches - black - that I couldn't cover. I spent 10 days walking around, looking like an extra in a slasher movie.
A couple of years later, I had another mole removed from my shoulder because it looked suspicious - it was fine, fortunately - and the dermatologist covered it with gauze, using hypoallergenic tape. My shoulder looked so much worse from the tape than the excision site ever did!
So now, I'll only use tape if the medical person insists and then I take it off again as soon as I'm out of their sight.
