Overview
Raynaud's is common and usually harmless. In some people it is linked to an underlying condition such as scleroderma or lupus.
Symptoms
- Fingers or toes turning white, then blue, then red
- Coldness, numbness or pins and needles
- Throbbing or pain as blood flow returns
- Rarely, sores on the fingertips
Causes and risk factors
Primary Raynaud's has no known cause. Secondary Raynaud's is linked to autoimmune diseases, vibrating tools, smoking and some medicines.
Diagnosis
Diagnosis is based on symptoms. Blood tests and nailfold capillaroscopy help look for an underlying condition.
Treatment
Treatment includes keeping warm, gloves and warm socks, stopping smoking, managing stress and medicines that widen blood vessels.
When to see a doctor
See a doctor if symptoms start after age 30, are on one side only, are severe, or you develop sores on the fingers.
