I have this too. I did ask the Dr. and he checked it out. He said it doesn't look like a yeast infection but it looks like chapped dry skin. He said that it could be from my liners. Some days I don't really have any itching and others, like last night, OMG it is unbearable. I couldn’t fall asleep for like 2 hours it was so itchy and painful I wanted to cry. He told me that I could use vagisil as it will help with the itching.
It sounds like we're in the same boat. I had to literally ice down my vagina earlier. I felt like I was going to go insane! Now it just feels raw and hurts. Itching is a tad better right now. I wear liners all the time and feel like I might not change them often enough (gross, sorry) so maybe that is the issue. I'm just going to keep at it with the vagisil and hope it goes away. Sucks.
