Whitepusbeard: I don't think there is such a thing as a 7 year yeast infection on dry skin. There is a certain type of environment in which the yeast must have to survive; such as a warm, moist, environment and in which there is a constant combination of the two. I am not a doctor, nor do I claim to be, but it could be some other form of dermatitis. Your best bet is to:
A. Buy over the counter Monistat. Rub it on and see how that works.
B. Try Skin Tight, it is an over the counter product (Beauty Supply Stores, CVS, & Wal-Mart sells this) that dries out ingrown hair
C. Go to the Dermatologist and simply let him examine you and tell YOU what it is. Do not provide a guess to the Doctor at what you think it "could" be. Let HIM tell YOU what it IS.
I saved the Dr's office for last, since your condition has persisted and you have gone this long without treatment...
