Help.

I haven’t had a yeast infection in a very long time. Atleast 10 years. Well I got new razors and I shaved and my clit is so itchy now and it’s spread down near my vagina opening. The razors have these strips on them so I’m thinking something from in them irritated me or body wash got in that area while I was washing the rest of my body (I don’t use scented anything down there) BUT I’m so damn itchy, like tearing myself open scratching & I don’t have an appointment until Wednesday with the gyno. What can I do? I’m going to continue using the itch cream that I have but that only lasts so long and I end up miserable again. Better throw in that I don’t have any STDS while I’m at it. Thanks in advance.
