I have a Swollen vein that leads to a sore like bump

I have a Swollen vein that leads to a sore like bump it starts in the middle and goes along the edge of my right labia and towards the middle of the entire length of my "lady area" is when it ends and turns into a bump about the size of a bead. I can definitely feel the swollen vein slight discomfort when I squeeze it but the bump does hurt when it's squeezed or when applying pressure. I'm 21 years old, I haven't had sex with my husband at all recently because he's off on duty and this is the first time I have a swollen vein though I've had the bump before, it's usually goes away. I haven't had any children yet and I don't have medical insurance at the moment. Does anyone know if it's harmless, is there something I can do to bring the swelling down? I'm kind of weirded out by this (O_o)
