This is only slightly sports related, and it happened a long time ago. I was 7 months pregnant and had been doing aerobics for a couple of years. I noticed my left foot was really hurting me, especially my left toes. I suffered for about a month, and when I went to my doctor for my monthly check up, I was convinced this was from driving my standard car, with a clutch. I even began calling my condition "clutch toe."
The ob-gyn looked at my foot and told me I had athlete's foot! I had been hanging around in my sweaty athletic socks (cotton, of course back then) after coming home from the gym. Problem solved.
