M.,
I bet it is a vericose vein. Ask your OB. I had that during my second pregnancy. Who knew, huh? It was a swollen vein between the vag. lips. It was VERY uncommfortable if I was standing. It only felt better if I put pressure on it (which isn't a pretty look). I was recommended to get some "special" underware, but I never could figure out how that could possibly help so I didn't get them. The whole business went away the moment my daughter was born. Hope you find something that works for you!
