Check out the Trigeminal Neuralgia page on this site. There is a percentage of MSers who also suffer from TN. I've got Atypical TN. (At least that's the theory so far) I have pain like a burning needle being pushed through my eardrum, and the ear itself is so tender, the slightest touch makes me cringe. Sometimes the pain radiates behind my eyes and down my neck. I do hope that is not the case for you.

I know heat really helps. And relaxation, whatever you can do to relax your muscles (which of course are tense because you're in pain). And sometimes, marijuana has been helpful. Pth the three together and you should feel better.
