Altitude

Hi,

I live in Colorado and have MS. Over the last couple of years, we have visited family in Michigan, and while we were there, my symptoms have gotten significantly better! I am assuming this has something to do with the lower altitude. Right now, my family and I are considering a move to Michigan. My concern is that over time, my symptoms will either come back, or possibly worsen. Does anyone have any experience with this? Any advice, thoughts or ideas would be very much appreciated!

Thanks!
