I have noticed that my feet smell really sweet (for years now), and I am wondering what is causing it. My sweat in other places (such as the armpits) do not have this scent. I am fairly sure that I do not have AIDs, as neither of my parents have AIDs nor have I had sex with someone else. I am fairly young (and my feet have been smelling like this for as long as I remember, which is when I was 10), and not particularly active. Only one family member (that I am related to by blood) has died from cancer, most likely because she was a heavy smoker. Is there any cause for this? (I researched into it slightly before asking.)
