What is it?

What is Raynaud’s phenomenon?

Raynaud’s phenomenon is a condition that causes the blood vessels in the hands and feet to narrow, decreasing blood flow. When this happens, parts of the body—usually the fingers and toes—become cold and numb, and change color (usually, to white or blue). An attack usually happens from exposure to cold or stress.

What are the types?

What are the types of Raynaud’s phenomenon?

There are two types of Raynaud’s phenomenon.

  • Primary Raynaud's phenomenon is the more common form. Doctors do not know what causes this type.
  • Secondary Raynaud's phenomenon is usually caused by another disease or problem, such as a disease like lupus or scleroderma. Exposure to cold or certain chemicals may also cause this type of Raynaud’s. The secondary form can be more serious than the primary form.
What are the symptoms?

What are the symptoms of Raynaud’s phenomenon?

Raynaud’s phenomenon happens when “attacks” affect parts of the body, especially the fingers and toes. The attack causes the fingers and toes to turn pale or white and become cold and numb. Getting cold is the most common trigger, such as when you grab a glass of ice water or take something out of the freezer. Entering an air-conditioned building on a warm day also can lead to an attack.

An attack may last a few minutes or a few hours, and pain levels during the attack can vary. When you warm up, your skin may tingle or burn.

For many people, especially those with the primary form of Raynaud’s phenomenon, the symptoms are mild. People with the secondary form tend to have more severe symptoms.

  • Mental health professionals, who can help people cope with difficulties in the home and workplace that may result from their medical conditions.

Living With It

Living with Raynaud’s phenomenon

Most people can control Raynaud’s phenomenon by making lifestyle changes. The following tips can decrease the number of attacks you have and how bad they are.

  • Keeping your hands and feet, as well as your entire body, warm is important.
    • If it is cold outside, try not to go out.
    • If you go out when it is cold, dress warmly, wearing several layers of clothing. Be sure to use a hat or hood. Consider heated gloves or hand warmers.
    • Protect your hands with gloves when you handle cold or frozen items.
    • Bring a sweater or jacket if you go somewhere that may be air-conditioned.
  • If you smoke or vape, talk to your doctor about making a plan to quit. Nicotine can increase the chance of an attack.
  • Some medications can bring on attacks, so talk to your doctor about those you take and before starting any new ones.
  • If an attack occurs, place your hands or feet in a warm place, such as under warm (not hot) water or under a heating pad. You can also warm your hands by whirling your arms in a windmill pattern or placing them under your armpits.
  • Because stress can bring on an attack, learning how to manage it is important. Meditation, deep breathing, or other relaxation techniques may help. Seek help from a mental health professional if you still have high stress levels.

Remember to visit your health care providers regularly and to follow their recommendations.
