There's no way to diagnose online. If you're concerned about this then you'll need to see your doctor for a diagnosis.

Good luck.

This kind of sounds like a swollen bartholin's gland which can be due to a number of things but is also closely associated with STD's like gonorrhea and chlamydia.

So what you need to do is to make an appointment with your gynecologist and have it properly looked at. If it is a bartholin gland cyst they'll probably want to drain it, which is something you cannot do yourself.

Waiting if it's something serious will only make it worse- so go see a doctor.

Good luck!
