Is It Possible To Develop A Bump On Ones Vulva

Is it possible to develop a bump on ones vulva due to underwear? I shaved down there on Saturday and wore pretty tight underwear that cut into the crease between my vulva and thigh. The following day the creases between my vulva and thigh were extremely itchy more than usual. I checked them and they were irritated (probably from scratching) but no bumps or anything. On Monday I check again and there was a bump in the crease about the size of a pea. It is smooth and flesh colored but a bit pink when irritated. It can get a bit irritated when I wear underwear. There is no bleeding or pus as of yet. I plan on going to the doctors but just wanted to get an opinion in the mean time.
