Need to see the doctor

Woke up yesterday with a itchy bump on my head, behind my left ear. Through the day it itched, throbbed and caused tingling that radiated from my ear, up to the top of my head and down to my shoulder. I went to the pharmacy last night to get some itch cream, but the pharmacist recommented that I not treat it and see the doctor first thing this morning. Her point was that by treating it now, it would mask some of the symptoms and make it harder to diagnos. Woke up this morning, it is very uncomfortable and I now feel itch and tingle under my right ear as well, although I dont have any pain or bump on that side. I'm going to see the doctor first thing this morning and have her look at it.
