Skene's cyst?

I'm 20 and sexually active. I recently noticed the area right above my clit was swollen and it's causing me a lot of pain. The gynecologist said it's a Skene's cyst but didn't give me much information except to put ice packs on it. I'm on antibiotics and pain killers but I guess I'm wondering if anyone else has had it and what caused it and how long it took to go away?
