mysterious rash on neck

I awoke one morning to find a small dime size itching area on the side of my neck. it was very red and many asked if it was a "passion mark." It itched worse and worse in passing days  and involuntarily i found myself scratching it in my sleep. soon i noticed that my ear on the same side  contained the same type of rash. my ear and neck are now very painful and it is rare that i dont awake to a bloody pillow in the morning. The rash has now escalated to open wounds for the most part and sometimes drip a clear odorless liquid. I am treating this several times a day first with peroxide and then aintibiotic  and benedryl ointments; none seem to help. I feel as if my left side (ear and neck ) are decaying. Also i should mention that it seems it may be spreading around my neck and possibly underneath my eye . I have ceased wearing any jewelry in case of possible allergic reaction. please help me. i would appreciate any advice or information given. thank you kindly...
