Can Lidocaine Allergy Side Effects Cause Throbbing Pain In Mouth And Gums?

Hello, I've been told that I am allergic to lidocaine. When I had a shot of lidocaine mixed with cortisone, my skin turned red and very warm. I'm going to have oral sugery in a few weeks and I told my doctor about my reaction; so he decided to give me a couple of lidocaine shots in my mouth to see if I had any kind of reaction. Well I didn't right then, but a few hours later, my mouth was throbbing and it felt as if all my teeth were going to fall off! Is this normal? Should I ask to be completely put under for oral sugery? As if now the plan is to use lidocaine shots and laughing gas....
