Raynaud's Phenomenon

Key Points

Overview

Raynaud's Phenomenon is a common condition where blood vessels in your fingers and toes temporarily narrow, reducing blood flow. This causes them to change color, feel numb, or tingle, especially when exposed to cold temperatures or stress. It affects your blood circulation and is often manageable with simple self-care. While often harmless, Raynaud's can sometimes be linked to other health conditions, certain medications, or long-term use of vibrating tools. Symptoms can also affect ears, nose, lips, or nipples, making these areas feel cold and numb. Episodes typically last from a few minutes to a few hours. Most people can manage symptoms by staying warm and avoiding triggers. In some cases, a doctor may prescribe medication to help improve circulation and reduce the frequency or severity of attacks.
