It is outside, for now, but here is the answer to your question, because we help everyone. Raynaud's is a condition where small blood vessels in your extremities (usually fingers and toes) overreact to cold temperatures or emotional stress by temporarily spasming and restricting blood flow. This causes the affected areas to turn distinctly white or blue, and they may feel cold, numb, or painful.The Three Phases of an AttackDuring a "Raynaud's attack," the skin typically goes through a specific cycle:White Phase: Blood vessels constrict, cutting off blood flow. Affected digits turn pale or white and feel numb.Blue Phase: The area turns blue or purple because the tissues have used up the remaining oxygen.Red Phase: As the blood vessels relax and blood rushes back, the skin turns bright red, often accompanied by throbbing, tingling, or a burning sensation.Attacks can last from a few minutes to several hours and in rare, severe cases, reduced blood flow can lead to skin ulcers or tissue damage. Please see your physician regarding what can be done . Good luck and God abless
