This is by far the most horrible feminine product on the market. I had a mild-moderate yeast infection that I wanted to start treating during the day. I used this product around 1:30 pm and felt some initial relief; however by 4:30pm I was experiencing the most horrific burning pain inside that I had to hold back tears and cancel the rest of my day. It lasted all through the night with no reprieve; I am now on my way to the ER after nearly 24 hours of the worst hell of my life. MY POOR VAGINA.
