This is an interesting one Dave.
I didn’t used to think there was a connection, but I was reading a book which was email conversations between a group of American women with MS, and one of them talked about having red & blue legs. She had asked her neuro about it and he said it was connected to MS. Something about the nervous system not sending the right messages to the capillaries.
Since then I have noticed a few posts on this forum saying the same thing… red a blue colouring to different parts of the body and feeling cold to the touch.
So it seems that it could well be an MS thing for you.
You will find that sometimes we can work out an MS connection but your neuro or MS nurse won’t necessarily agree. I think all MS health professionals should have to read this forum every day as part of their contract!
But it would be worth asking in case there’s something that could help. I’m trying to think if I know of anything, but nothing comes to mind. Might be worth posting on EL to see if anyone knows something that’ll help.
