Every spring, I get a rash on the backs of my knees which is hot, bumpy, its red and very itchy. There is no over the counter medicine that has ever helped me, so for years, I just suffer through the 2-3 months that I have it. Sometimes the area gets dry. I have been having this happen since I was 6 years old, and I am 34 now. If I was never able to count on anything else, I can always expect this rash to come back like the terminator.
