Hi I am 34 years and in 2012 got diagnosed with relapsing remitting multiple sclerosis. One symptom that is really sore and now preventing normal life eating, drink etc is that it feels like over producing saliva so I'm forever sucking my tongue. It often feels like the tongue swells as well so I often bite it but because tongue is always moving it like a whiteish friction burn. Please help.

Thanks
Valerie McHarrie
