Phantom Itch

I had a little dentistry done today, namely a crown and a filling replacement. The teeth in question were adjacent to each other, so the amount of anesthesia used was enough to make half my face numb for six hours. The problem came about 6:00 PM, when I experienced an itch on my lip. I went to scratch, but the spot where I thought the itch was located was still numb. I could have scratched until I bled and I wouldn't have felt a thing! It was, without exception, the most frustrating itch I have ever experienced. I could touch the very spot of the itch, and yet I couldn't scratch it.
