• Raynaud's Disease

    Raynaud’s phenomenon (Raynaud’s, or RP) is a condition which reduces blood flow to the extremities. It reduces blood flow to the extremities (usually the fingers and toes), causing the small blood vessels go into spasm in cold temperatures. As the fingers and toes warm up, the skin usually turns another colour such as red or blue, then returns to normal.

  • Causes of Attacks of Raynaud's Disease

    Attacks of Raynaud’s are typically caused by exposure to cold temperatures, and may last anywhere from a few minutes to a few hours. In some patients, the attack lasts longer than a few hours. Other things that can trigger attacks include injury, emotional stress, smoking and hormonal changes. In treatment  your pharmacist,  is the right HCP to make sure it’s the right medication for you.


    Patients are at a higher risk of developing Raynaud’s if they have had a previous injury to the fingers and toes, such as surgery or frostbite. People who work in professions where they perform repetitive actions or experience vibrations, such as using a drill or jackhammer, are also at a higher risk. A local chiropractor may work with your local massage therapist and your local physiotherapist to create the best health or rehabilitation plan for your situation. 

    Experts don’t understood what causes the blood vessels to become more sensitive to cold temperatures and other triggers. However, it’s believed the disease is related to the immune system because Raynaud’s can be associated with autoimmune or connective tissue diseases. Local Rheumatologist Pregnancy can be more complicated in women who have Raynaud’s phenomenon and an underlying autoimmune disease. Some women are at risk of multiple miscarriages.

    In some cases, doctors will use medications that lower blood pressure to help relax the blood vessels if you have severe Raynaud’s. We typically reserve those medications for patients that have very severe symptoms. If you have Raynaud’s, or you think your Raynaud’s is getting worse, please speak with your family physician.

  • Primary and Secondary Types of Raynaud's

    If you have primary Raynaud’s, there is no associated underlying autoimmune disease, but it can run in your family. Women in their 20s or 30s are most commonly affected, and it occurs more often in young women who are thin. Secondary Raynaud’s occurs alongside a secondary autoimmune disease like lupus, scleroderma or rheumatoid arthritis. This type of Raynaud’s is usually more severe than the primary type, and the symptoms may worsen over time.

    Secondary Raynaud’s is typically associated with underlying autoimmune diseases. Nearly all patients with systemic sclerosis (scleroderma) also have Raynaud’s. Local Rheumatologist
