A Persistent Knee Rash

DEAR AUSTIN: I have a rash. It's on my right knee. I've yet to have a conclusive diagnosis. Lotion will ease the itchiness, and the $400 prescription creme will decrease redness but it never goes away. I'm not a shorts person, I wear pants, and I don't kneel excessively or rub it on anything. I don't know what to do.
