Hi Bill, welcome to NeuroTalk.
So sorry for your DX of PPMS. We have some wonderful members here who have your DX and I hope they speak up and compare notes with you.
I am SPMS, but this late in the game, for me, there is little difference in the two. After some 45 yrs with symptoms of MS, I'm pretty much done walking too.
Come on in and join us at the Stumble Inn, where we are a little less sicky and a bit more ourselves. Or join us where ever you wish.
We are here for you and us.
