Is there any chance you could go to an ER and get them to inject some long acting anesthetic? Or have you tried lidocaine patches? I have them but they don't stick to my neck or anywhere there is hair. I really need a lido creme. Or, have you tried putting capsacin creme on it? Repeated applications may help you get through till the 4th. Having to start a new job while you're in so much pain really is rough. Hang in there and take care.
