Don't get all twisted about this...you won't know what's going on until you see them. So try to breathe, distract yourself, and know that you'll eventually find out what's going on.

I know it's easy to say this...but I've been there after several years of having one thing after another blamed for my sxs, until I had a bad enough exaserbation to get them to dx MS.

Try to stretch, do relaxation breathing, and be as active as you can until you go in.

And know that we're all here for you with info and hugs
