Hand pain

Do you sometimes notice an odd white, blue, or red coloration in your fingers or toes? It might be a sign of Raynaud’s phenomenon.

What Is Raynaud’s Phenomenon?

What causes Raynaud’s is unknown, but the process is well understood. A vascular activity called vasospasm causes the blood vessels in the fingers and less commonly the toes, ears, lips, and nose to overreact when exposed to cold and stress. You might also experience cold or tingling sensations in the same areas.

Raynaud’s Phenomenon Symptoms and Diagnosis

Coloration of the fingers and toes is one sign of Raynaud’s. To determine whether you have primary or secondary Raynaud’s, your health care provider may conduct a nail fold capillaroscopy test.

Using a microscope, he or she looks for deformed capillaries in the fingernails or toenails. Their presence may indicate primary Raynaud’s and the doctor may order blood tests to be sure.

Secondary Raynaud’s is diagnosed if some other health condition—artery or connective tissue diseases, for example—causes the phenomenon. The primary form has no other source.

Raynaud’s Phenomenon Risk Factors

Predominantly occurring in women, primary Raynaud’s phenomenon occurs between ages 15 to 30. The secondary form of Raynaud’s usually begins after age 40.

A third of people with the disease have a close relative with Raynaud’s. Lupus and other medical conditions increase the risk for developing it. Workers who routinely traumatize their hands operating machinery or are exposed to such chemicals as vinyl chloride are also at risk.

Living with Raynaud’s Phenomenon

Cold temperatures, smoking, and stress aggravate Raynaud’s phenomenon. You can help reduce the number of attacks and improve your overall health by following these tips from the American College of Rheumatology (ACR).

The ACR also advises those with Raynaud’s to pay special attention to their hands and feet. That means having proper-fitting shoes, avoiding injury, and not wearing anything that constricts the blood vessels. Avoid going barefoot, always wear gloves (mittens are best) in the cold, and practice good nail care.

Raynaud’s Phenomenon Treatment

To relieve an acute attack of Raynaud’s phenomenon, the ACR advises “the first and foremost action” is to gently warm affected areas. During an acute outbreak:

  • Wiggle your fingers and toes
  • Make windmill movements with your arms
  • Warm your hands under your armpits
  • Immerse your hands and toes in warm water
  • Massage the affected areas

Some medications used for treatment prevent tissue damage and reduce the number and severity of attacks. Medications also treat underlying health conditions that cause secondary Raynaud’s. Nerve-blocking injections, surgery, and even amputation may provide the only relief for those coping with the most severe forms of the disease.
