ppppffffttttt! That's why with PPMS I never get MRIs anymore, if something shows up, well that explains it they say. If nothings shows, it can't be MS related. I hate MRIs - I'm middle-aged, I don't have time to waste! My neuro was on vacation once, the covering regular type neuro told me when I called in great pain "MS doesn't cause pain". @#$% her! Oh yes it does.
