Suggest Remedy For Itching And Burning Ear

got a new pair of glasses several weeks ago. for the last two weeks I've experiences severe itching and burning behind, on top of, and on the skin on the back of my ears. the skin looks red and slightly bumpy. Have had glasses adjusted thinking they were too tight to no avail. Treated with cortisone cream. No help. It seems to be getting worse. Have stopped wearing those glasses though.
