Did anyone here ever got their front upper teeth treated?

Going to have an upper front tooth treated next week and I'm DEAD SCARED of the anesthesia. Really, really, really scared. I've read so many horror stories by now that it's not even funny.

Can anyone here share their experience? Is there that much pain? What does it feel like, does it sting as if you were putting alcohol on a wound, or does the pitch hurt a bit more than the other injections? Or does it feel like an eletric shock?

Thanks y'all.
