Hi,
it could be VA . But if it does not improve try your local Sexula health clinic as they can test for Cytolitic Vaginosis, lactobacilli over grwoth, and bacterial vaginosis , all of which can cause itching. Yes VM daily can help some to rebalance the inside. Have a look with a mrror. Make sure you know what looks normal for you. Use hydromol fore washing and aviod soaps and bubble bath, all of which can upset the flora. Sleep with no knickers and go knickerless when you can. I hope this helps. Having an uncomfortable V is miserable!
