I Went And Got A Pedicure A Couple Weeks Ago.

I went and got a pedicure a couple weeks ago. The next day I noticed a small rash on my right ankle. It looked a lot like razor burn. It didn't bother me until the othe day it got itchy. I scratched it. Not rough but when I did the ski just fell off. It stung really bad and the days proceeding for very red and yellow gunk. It has finally scabed over but now the rash is spreading and is on my other foot now. When I wear shoes it itches really bad everywhere the shoes touch. Any ideas?
