Tongue pain

This symptom went dormant for a couple of years but now it’s recurring, dammit.

Searing tongue pain and huge saliva production; I immediately need to spit but can’t because my tongue is gripped in intense pain.

Then, like an MS hug, it goes away.

Anyone else? What have you found alleviates the pain? I nearly passed out earlier, but of course I’m ok now, thank goodness.
