I was diagnosed with PN six years ago. My (half) sister has had MS since we were in our 20's. (I am 52, she is 46). Mine is very very painful, hers somewhat painful.
I was describing some of my "new" symptoms to her today at lunch, and she told me it REALLY sounds like I have MS!

I was only tested for MS one time, six years ago, when I was first diagnosed. They did an MRI. There was never a follow up. However, my PN has slowly progressed up my legs to my knees. Her MS is the kind that comes and goes. She doesn't work, because she has more bad days than good lately. However, she doesn't have to use a wheelchair yet.

It was an interesting lunch though we both walked in using canes, and her mom (my step mom) walked in all healthy at 68 years old!

I couldn't wait to get back here to post this to get some feedback from you guys! I posted this (a version of it) on the MS board as well.

Thanks everyone for your support!
