The roof of my mouth is so sore with ulcers after chemo I can hardly swallow I've used the mouth washes it's so awkward to get to it think I'll go to chemist tomorrow see if they have a spray.
Hi! I remember having very bad mouth ulcers when I was on FOLFOX chemo 3 years ago and the only thing that would relieve it was baking soda dissolved in warm water (about a teaspoon in a cup). The relief didn't last very long and it was still very painful to eat but it still eased the pain for a bit.
