Hi, I am on day 5 of nystatin for oral thrush. I take 5ml of nystatin 4 times daily and the white stuff on my mouth went away. It seemed to be getting better but today I saw a canker sore on my tongue and I began to get worried that the medicine isn’t working?

Mouth infection is a common side effect of this Rx. If your canker sore persists and causing you lots of discomforts, then you should be worried.
