So I got my 5% Lidocaine topical gel and applied it tonight. I wore gloves and smeared 1/4 of a small tube of gel all over my vestibule and also a little ways inside of my vagina. I then waited 20 minutes. Not only did it not numb me, but I experienced intense itching and burning. I immediately wiped it off, then took a shower to get rid of the rest of it. Even now, after the shower, I'm still feeling kind of raw and itchy.
I'm not sure whether this means I did not apply it correctly, or if I had some kind of allergic reaction. I'm going to call my doctor and find out.
