Thanks so much for your interest and support, myeamans!

What's happening with me? Yes. lots of burning and leg pain, although the latter doesn't sound to me exactly like what I've heard described for PAD. The muscles hurt when walking, especially climbing stairs, but the muscle pain stops immediately when I stop moving, not a lingering ache like PAD symptoms say. Burning is almost all the time.

Color change: GP noticed it, I didn't, and said it was Raynaud's, but nobody's ever paid any attention to it until I mentioned it to my latest neuro. He didn't really look at it, but suggested a calcium channel blocker. It sounded like it invited more trouble than the condition causes, so I said "nope!"

I will keep in mind what you said about your experiences. Thanks again!
