question: I was bitten by a fire ant a couple of years ago and had an allergic reaction. Since then, I ve had a couple of mild cases of cellulitis during which my foot (and the last time, my leg) will swell. There is still a small nodule which looks like a wart or callus on my right toe. Every once in a while, it gets irritated and swells up. Should I see a dermatologist for this? My general practitioner has not been successful in preventing the flare-ups.
