What Is Raynaud's Phenomenon?
3. How Is It Diagnosed?
Many people can diagnose Raynaud’s phenomenon in themselves because its symptoms are relatively distinctive. However, others may live with pain, tingling and numbness for years before seeking a diagnosis. A complete medical history and physical examination can uncover the disorder in most cases.
Doctors will look for signs of discoloration of the hands and feet that indicate reduced blood flow to those areas. They may also check for physical sensation changes, such as a feeling of pins and needles when affected areas are touched. A cold challenge test can complement these observations.
