Hi and welcome! Sorry I'm late to the thread, but you've got a ton of advice. Glad you found us.
Yep, stress can make things worse for us. I was also wondering if you had any balance issues.

I know that my back and hips hurt for awhile from the compensation I was doing for my wacky legs and PT helped a little with it.
There's a lot of great info out there. I have the book previously mentioned by Natalie and I have "Multiple Sclerosis for Dummies". Both of those helped a lot. The NMSS also has a lot of good info on their site.
