My hands and feet are nearly always cold. Maui, sunny day sitting on the beach, cold feet. My hands never look quite as radical as yours, but the dermatologist says it’s Raynaud. When I have to handle frozen food or whatever it literally hurts in my chest. Kind of a lot. Do you get that too? … Weird how I sometimes forget to ask the internet about this stuff but I just googled and apparently chest pain isn’t uncommon.
It’s an immediate response to cold hands. Even handling refrigerated chicken, not just frozen stuff.
