Pain during orgasm?

I wasn't sure where to post this (and I think this is actually my first post on eve) but I'll try here... For at least 2 or 3 weeks now, as soon as I orgasm I get a sharp pain in my clit that lasts until the climax is over. I'm not sexually active and I don't even masturbate very often, but I've also had some vaginal itching and light yellow discharge on and off for months now.

I've heard of clit pain being caused from overstimulation but I feel like this might be a recurring infection? I'm going to talk to my doctor, just wanted to get opinions and see if anyone else has experienced something similar.
