... for a day and a half. I applied some Vagisil before going to the store to buy Monistat to start curing and when I got home and took a shower getting ready to apply it I noticed my left labia was swollen. I still used the Monistat 1 and I used Vagasil for the pain but I still feel itchy and my swollen labia has not gone down. It has been a couple of hours already.
