What causes an itchy blister on the vagina?

default
Posted on Fri, 4 May 2018
Question: Hi a few weeks ago the outside of my vagina was really itchy, so I scratched it and then I noticed there was some blood. So I thought I burst a spot or something. Now that area looks like a blister but without the bubble on top it’s the same colour as my flesh. It sometimes forms a white crust? And gets itchy. Should I be worried.

I’ve been with the same partner for 4 years.
