I don't post often but I really enjoy reading everyone's posts and insight to not only MS but life in general! ?So what better place to come for info than here???

I have been on Avonex going on 3 years with little or no progression to speak of... but in the last few weeks I have been have dizzy spells. They come out of nowhere and last only 10-20 seconds. It's almost like I'm uncoordinated all of a sudden. My question is should I call my neuro and ask for an MRI since I've not had one in 3 years. Maybe the Avonex isn't working anymore...?? Or do I chalk it up to this crazy disease we live with??

Thanks for your input!
