Thank you so so much. In agony for two days with multiple canker sores. Applied mustard. Yes, some initial discomfort. Within two minutes, complete relief. THANK YOU AGAIN:)
For whatever reason if you put Mustard directly on your canker sores it burn then the pain is gone. Instant relief. I don't know if it heals anything but it sure feels better for a while and you don't have to run out and buy anything special.
