Hi John,
Just wanted to let you know I have the same problems. I’m 68 and was diagnosed about 2 years ago. My left leg has wasted, but fortunately my right leg and other limbs are still in pretty good shape. I can walk with two canes or a rollator walker. My left foot and ankle swell when I’m up and about for too long, and they get very cold, even in summer. My neurologist suggested I see my PCP about it, but otherwise had no advice, other than to say it’s not uncommon. Thinking I’ll try heated socks and/or compression socks.
