Hi, Soibhan . . . I did look up Raynaud in my home medical encyclopedia and my fingers and toes do not change in color either when cold or when warming up.
My husband mentioned tonight that he was having problems with his extremities after being in the cold all day today as well. He had frost bite of the toes and fingers when he was little. I had forgotten about that. I did, too, but not severe.
I will mention Raynaud and frost bite to my doctor though I will not be seeing her until March.
Thank you for your help!
