After looking in my mouth, my GP said, I think you have thrush. A dentist had said an X-ray showed no tooth infection was causing the bad taste. GP prescribed nystatin. After taking it the bad taste is worse than ever, especially in the morning, and the area behind my top and bottom teeth feels rough like what happens when you bite into a too-hot pizza. Nothing tastes good especially morning coffee.
Could the nystatin have done this and does it go away?
Thank you.
