What is Raynaud's disease?
Raynaud's disease is also known as Raynaud's syndrome or Raynaud's phenomenon. It is a condition in which small blood vessels in extremities like fingers and toes overreact to cold weather or emotional stress, causing reduced blood flow, color changes, numbness, and pain. The Raynaud phenomenon is sometimes associated with high blood pressure and musculoskeletal and skin diseases such as scleroderma, lupus, rheumatoid arthritis, and Sjögren’s disease (Garrick, 2017).
Anyone can get Raynaud’s phenomenon, but certain factors increase the risk. The primary form has no known cause, affects more women than men, usually occurs before age 30, and often has a genetic link. The secondary form is associated with medications for migraines or attention deficit hyperactivity disorder (ADHD) - and environmental factors like operating vibrating tools often.
Signs and symptoms of Raynaud's disease
Some common signs and symptoms of Raynaud's disease include:
- Color changes in fingers or toes, typically turning white, blue, or red
- Numbness or tingling sensation in affected areas
- Pain and discomfort
- Cold extremities
- Difficulty moving affected fingers or toes
In severe cases, ulcers or gangrene may develop on the fingers or toes. Seeking medical attention if you experience any of these symptoms is essential.
