I think I've had one nearly every year since 2002.
Get your docs fax number and when you have something strange pop up....fax him/her with the details and let the doc decide if you should go in.

This is what works best for me. Also I have had many odd things happen...then disappear and they are just a part of the disease. My doc said it has something to do with lesions that act up without causing major symptoms.
I have a head full of lesions but minimal disability. But once in a while one of those lesions decides to pick on me.
