Raynaud's Phenomenon

Cold hands might signal more than the weather — get your blood flow checked.

What is Raynaud’s Phenomenon?

Cold fingers, numbness, and color changes are common signs of Raynaud’s disease.

It is a condition that occurs when blood vessels of the fingers or toes get narrowed in response to cold or stress, restricting blood flow. This causes color changes, numbness, or tingling in the affected areas.

Common Symptoms

Skin color changes.
Fingers or toes feeling cold or numb
Tingling or throbbing, when blood flow resumes
Skin ulcers and gangrene
Episodes triggered by cold exposure or emotional stress

When to see a Doctor

Frequently experience color changes or numbness in fingers/toes
Have sores or ulcers on fingers or toes
Have a history of autoimmune disease (e.g., lupus, rheumatoid arthritis)
Develop painful or long-lasting attacks
Notice skin ulcers or persistent coldness in extremities

Early detection is important for managing the condition and preventing further complications. Schedule a consultation today.
