I had this too. It felt like my pubic hair was spiked and very dry. I ended up buying Vagi-Gard at Walmart, it is OTC and I only had to use it a few times to get major relief. I don't need it anymore now.
This is a bit gross but (just in case this happens to you too) around the same time I got lumps in my labia and under my arms. I took care of those by taking epsom salt baths and eventually they went away completely, thank goodness.
My mammogram showed benign changes so I think I just went through an inflammation period, anything that could get inflamed got inflamed, or so it seemed!
The glands in the pubic and underarm region develop at puberty (I think) so it kind of makes some sense to me that they would undergo changes at menopause. At least, this is how I reasoned it to myself.
Is this peri related? I think so but have not really read about anyone else having this wonderful symptom!
Hang in there, I feel for you.
