Ca or alpha blocker.: This can be due to circulation difficulty, or it might be a symptom of hypothyroidism or vasculitis. There are vasospastic disorders, like raynaud's phenominon, that are triggered by cold exposure, with blanching, cyanosis, and redness, so the extremities must be kept warm. Calcium blockers like Nifedipine and Alpha blockers, like prazocin can help raynaud's. See your doctor and get tested.
