I am sensitive to cold also and I have one finger that turns white on my left hand alot.
I was told raynauds also by a neurologist years ago, but i believe its part of MS also.
This was the same doctor who i believed misdiagnosed me, i have had numbness on my arms & tingling for years...he told me it was coming from my neck

I Notice that I am much more sensitive to cold than I used to be and am getting a lot of numbness in my fingers and toes, too. Temperature sensitivity is very common with MS. Just a guess but I think if it was decreased blood flow that would be a circulation issue and tips of fingers and toes would turn blue. Stay warm! Get some good socks and mittens 😀

Look at Raynauds syndrome. I get it too.

Thanks!

I have sensitivity to the cold on my left side. My hand and foot is n the left are significantly colder than my right ones. My neuro told me that is because the ms has made the left muscles less effective and the more scales help the blood move around. I use hand warmers in my shoes when I have to shovel snow, and my husband bought me electric slippers that work great. I sleep with a hot water bottle for my feet too. I know my issue is not raynauds because it is only one side.
