Hi Morgana,
I have gone both routes: injectable lidocaine and topical EMLA cream. I had the same fears you do, so my initial clearing was done at Precision Hair Removal in Wilmette, IL under IV sedation and a local anesthetic. It is associated with Dr. Zukowski's FFS clinic.
They start an IV on you and give you a shot of narcotics, which is supposed to put you in a "twilight sleep". Yeah, right. I got a good buzz, for sure, but when Dr. Z stuck me with the lidocaine injections in my scrotum and genital area, it hurt like hell. Still, that was the worst of it. Then Irina, the electrologist, goes to work while you are in a pleasant fog.
I had a complete clearing done in 4 1/2 hours, but it cost me $1000. Since I needed to do that at least three more times, it just wasn't practical for me to fly to Chicago and lay out that kind of cash.
Fortunately, the electrologist I was seeing in Alexandria, VA for my face also did genital electrolysis. I got a prescription for EMLA cream and slathered it on there at least an hour before hand and stuck plastic wrap all around my crotch. It was a breeze. Transcutaneous absorption in the genital area seems to be much better than on the face. I did five more clearings every five or six weeks, each taking less than an hour, and my SRS surgeon was pleased with the results.
The good thing about the lidocaine injection route is that the electrologist can really turn up the current and take her time finding and destroying the hair follicles. That made it possible for my local electrologist to sweep the area with a laser and then go after the few stubborn hair follicles by electrolysis, making it a quick process. On the downside, my scrotum was a red, scabbed, swollen mess and I was walking funny for a couple of days after coming back from Chicago!
