I have been plagued with raynauds for about a year now (53) and have problems with one of my fingers going completely "white" but the rest of my hands change from patches of white to red in the cold. If I squeeze my fingers when they are red they stay white for ages when they are cold. I also have it in my big and second toe but this also happens when I get in the bath & the temp changes. I can get it in my nose & nipples too!
I have hashimotos thyroid & fibromyalgia & arthritis. Can anyone help me to understand ?
