A member asked:

When cold, is there a reason for 1 finger to become numb and lose color regularly, even when none of the others do?

Vascular?: Previous injury to blood vessels could be the cause? Do you smoke? I would try treating this with low dose dltiazem, continuous release for symptomatic relief. It is not raynaud's. Cryoglobulinemia, cryofibrinogen, and antiphospholipid syndrome can causes this.
