Is There A Permanent Cure For Pain In Crus Of Helix Which Gets Crusty And Sometimes Bleeds And Is Very Painful?

I have pain in my Crus of Helix, it's gets crusty, sometimes bleeds a bit and very painful at times and keeps recurring sometimes in both ears. I have been prescribed Hyderm 1% cream in clotrimazole 1% which works for a little while but comes back in a few weeks, is there anything else I could use / do so it would go away permanently. I am on the phone at lot for work, so not sure if that makes it worse
