... hours after and then later that night I took another before bed. My burning is stIll present. I bought another pack and I am not sure if I should take it or wait couple days to start again. This is my first time using monistat 3. I called a doctor and they told me to buy monistat because I was having a burning and itching sensation while urinating. It was so bad to the point I would cry while peeing and be soo terrified of peeing again later.. please help its been almost 2 weeks
