Diagnosis of Raynaud’s Phenomenon

There is no single test to diagnose Raynaud’s phenomenon. Doctors usually diagnose it based on symptoms, in particular, on a description of a typical attack upon exposure to cold. Your doctor will likely also take a medical history and perform a physical exam.

Your doctor may perform additional tests to distinguish between the two forms of the condition. These include:

  • Nailfold capillary microscopy. During this test your doctor uses a magnifier to look at the base of your fingernails for signs of changes in capillaries (extremely small blood vessels), a sign of secondary Raynaud’s phenomenon.
  • Blood tests. If your doctor suspects that you have the secondary form, they may order blood tests that may indicate you have a disease that has been linked to Raynaud’s phenomenon, such as lupus or scleroderma. One of the more common of these tests is the antinuclear antibody (ANA) test.

Treatment of Raynaud’s Phenomenon

The goals of treatment for Raynaud’s phenomenon are to:

  • Reduce how many attacks you have.
  • Make attacks less severe.
  • Prevent tissue damage.

For most people with Raynaud’s phenomenon, avoiding getting cold prevents attacks and keeps symptoms under control. But if this is not enough, medications and, in some cases, surgical procedures can help.

Secondary Raynaud’s phenomenon is more likely to be serious and to need more aggressive therapy. If you have the secondary form, you may need to seek treatment for an underlying condition, if you have not already done so.


Preventing Attacks

  • Medications. While there are no medications approved by the U.S. Food and Drug Administration for Raynaud’s phenomenon, medications that have been approved for other conditions are routinely used to treat it.
  • Surgery. If you have severe Raynaud’s phenomenon, your doctor may recommend a procedure called a sympathectomy to destroy the nerves that trigger blood vessel narrowing in the affected areas. This is usually done by incision or injections. The procedure often relieves symptoms, but it may need to be repeated after a few years. 

Treating Tissue Damage

In serious cases, repeated attacks can lead to skin sores or gangrene (death and decay of tissue). If this happens, you may need to be admitted to the hospital for a few days and receive intravenous medications to rapidly improve blood flow and to treat infection. In rare cases, you may need surgery to remove dead tissue.

Who Treats Raynaud’s Phenomenon?

Raynaud’s phenomenon is primarily treated by:

  • Rheumatologists, doctors who treat diseases of the joints, muscles, and bones. Rheumatologists are also specialists in autoimmune diseases. They treat Raynaud’s phenomenon because it sometimes occurs in association with rheumatic diseases, like lupus.

Other specialists who may be involved in your care include:

  • Cardiologists, who specialize in treating heart and blood vessel problems. 
  • Dermatologists, who specialize in conditions of the skin, hair, and nails.
  • Mental health professionals, who can help people cope with difficulties in the home and workplace that may result from their medical conditions.
  • Primary care doctors, such as family physicians or internal medicine specialists, who coordinate care between the different health care providers and treat other problems as they arise.
  • Surgeons, including hand specialists, who may be orthopaedists, plastic surgeons, or vascular surgeons.

Living With Raynaud’s Phenomenon

In most people, Raynaud’s phenomenon can be controlled by making lifestyle changes. The following tips can decrease the number and severity of attacks you have.

  • Keep warm. Keeping your hands and feet, as well as your entire body, warm is important. It is often not enough to keep your hands and feet warm and you need to keep your “core body” (chest, abdomen, and head) warm, too.
    • 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, because you lose a lot of body heat through your head. 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 to an indoor setting that may be air-conditioned.
  • If you smoke, talk to your doctor about making a plan to quit. Nicotine in cigarettes and some vaping solutions can cause blood vessels to narrow, increasing the chance of an attack. Smoking also may cause permanent damage to blood vessels, which is particularly dangerous for people with Raynaud’s phenomenon.
  • Some medications can bring on attacks, so talk to your doctor about those you take and before starting any new ones. Medications that can bring on attacks include:
    • Decongestants that contain phenylephrine or pseudoephedrine.
    • Appetite suppressants that contain pseudoephedrine.
    • Beta blockers for high blood pressure.
    • Migraine medications that contain ergotamine.
    • Certain stimulant medications, such as methylphenidate, for attention deficit-hyperactivity disorder.
  • Act quickly to end an attack. 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.
  • Cope with stress. 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 these approaches do not work and you continue to experience high stress levels.

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