A yeast or fungal infection on the skin will manifest as a red rash, broken skin in places showing a trace of blood (looking almost like a scrape), and a burning/itching sensation.
It's rare to get one on the face. I would see your dermatologist. My dermatologist scrapes any rash I have, looks at the samples under a microscope and tells me whether it is a fungal infection within 20 seconds of looking at it under the microscope.
In 18 years rotating antibiotics, I have had only one REALLY BAD yeast infection and it was mainly because I initially treated it by putting Desitin on it which is the absolute worst thing you can do, because moisture feeds it. You need to keep the area of any fungal rash dry by using anti-fungal powders. A few other times I saw red patches in my armpits and legpits and quickly doused them with antifungal powder. I am treating a small one in the right legpit right now.
I have also gotten warts, which is a viral infection. Viral and fungal infections of the skin occur when skin bacteria is killed off by antibiotics. The principal is quite simple: each microorganism occupies space. When you kill off one, there is empty space and the others are eager to fill it up. When the bacteria leave town, the fungi and viruses in your skin, which you never saw or heard from previously but were always there, suddenly flourish in larger populations. The physical manifestation is seen in yeast infections and warts.
