is diflucan used by itself enough to cure a yeast infection?

I was wondering if taking the pill diflucan for a yeast infection would be enough to completely cure it, or would I need to use a cream for the outside? I took the diflucan 3 days ago (it says it can take between 3-5 days to work) and the discharge has stopped but my vulva is still very irritated and red. Would I need a cream for that or will the diflucan take care of it in a couple more days?

The cream is just to soothe the outside and the vulvular area. But the diflucan should be enough to heal everything, just give it time. When i get diflucan for my yeast infections that’s all i use because i hate how messy and sticky the cream is.
