How to treat persistent itchy rashes on the ear?

Hello doctor,

I have some rashes on and behind my ear. I have tried everything but it is still there for over one and a half months. I have been ignoring it because I get better quickly but does not entirely disappear, and right now is worst than ever. It is quite itchy and at night it is even worst. Sometimes I feel the itchiness inside my ear.

I went to an Otolaryngologist, and he told me to use Clotrimazole, but it did not work and turned worst. Another doctor told me it looked like herpes because sometimes when it is horrible, you can see little red bumps in the ear. I took Acyclovir and at the beginning looked like getting better, but it has not got better. I have not consulted a skin specialist yet.
