Raynaud's phenomenon

Very low urgency
--

Circulation impairment of the fingers and/or toes, where arteries become narrower and blood flow is limited.

The cause is known in some cases while in others is not identifiable, but it usually coincides with cold temperatures or stress.

The fingers feel numb and cold, turning white or blue.

The diagnosis is clinical and treatment consists of avoiding the triggers. On rare occasions, medication, or even surgery is required.
