Raynaud's phenomenon is common and does not usually cause severe problems. You can often treat the symptoms yourself by keeping warm. Sometimes it can be a sign of a more serious condition.

Raynaud's affects your blood circulation. When you're cold, anxious or stressed, your fingers and toes may change colour.

Other symptoms can include:

White fingertips caused by Raynaud's.Blue fingertips caused by Raynaud's.Red fingers caused by Raynaud's.Fingertips of a person with dark skin who's affected by Raynaud's.

Some people also find that their ears, nose, lips or nipples are affected.

The symptoms of Raynaud's may last from a few minutes to a few hours.

Raynaud's is sometimes caused by another health condition, taking certain medicines, or working with vibrating tools for a long time.

If you're not sure it's Raynaud's


  • keep your home warm

  • wear warm clothes during cold weather, especially on your hands and feet

  • exercise regularly – this helps improve circulation

  • try breathing exercises or yoga to help you relax

  • eat a healthy, balanced diet


  • do not smoke – improve your circulation by stopping smoking

  • do not have too much caffeine (found in tea, coffee, cola and chocolate) – it may trigger the symptoms of Raynaud's

If your symptoms are very bad or getting worse, a GP may prescribe a medicine to help improve your circulation, such as nifedipine, which is used to treat high blood pressure.

Some people need to take this medicine every day. Others only use it to prevent Raynaud's – for example, during cold weather.

A GP may arrange tests if they think Raynaud's could be a sign of a more serious condition, such as rheumatoid arthritis or lupus.
