<human>: 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.
<bot>: Thanks for asking in Chat Doctor forum In Short: Allergic reaction, bite, wart, callus and cellulitis are not related. Explanation: If you are having frequent cellulitis, something is wrong with your immunity. Callus is hardening of skin due to continuous pressure. Wart is a new growth from viral infection. I think you are confused with your lesion.  Go to dermatologist and get yourself examined for proper diagnosis and treatment and further prevention.  Good luck
