Nail fungus and numbness

I have, what I believe to be nail fungus on my left big toe.. I believe I got it from when I had a pedicure about 2 months ago… My question is, I have been having numbness on that toe also.. Can fungus cause the toe numbness?? I just noticed the fungus because my nailpolish was just removed from my previous pedicure.. I Plan on calling Dr but wondered could it be symptoms of fungus.. and also was told by our family dr, to use VICKS vapor rub for toe fungus 3 times a day?? Have you ever heard of that?
My daughter is a gymnast and had fungus and that is what he is having us use?
