My tongue has had a furry white coating with changing red patches for the past six months. I have been told it is related to PND from persistent allergies which cause my nose to be blocked and have been prescribed a steroid nasal spray. This has had no effect and therefore I am not sure if the diagnosis is correct.
I snore badly and suspect that I breath through my mouth throughout the night, which means that it gets dry.
Can anyone offer suggestions for helping?
