I had double vision and diziness as my first symptoms and was dx with MS three weeks later.

The breathing difficulties were not happening then but they are now. Much better than they were a couple of weeks ago and this is the first time I've had difficulty breathing since my dx.

I had pseudo exacerbation symptoms during the week my sister died. It was a horribly stressful time for me - I had a houseful of company, everybody wanted to be on the "go" constantly and all I wanted to do was sleep. That psuedo exacerbation lated five days.

I'm not sure there are any "guidelines" we can go by when it comes to MS - everyone is different.
