Raynaud's Phenomenon and Fibromyalgia
In addition to the many symptoms people with fibromyalgia have to face, including chronic fatigue, fibrofog, and persistent migraines, some also have to deal with Raynaud's phenomenon, a circulatory disorder that causes numbness and tingling in the hands and feet.
Raynaud's symptoms are typically harmless, but can be quite annoying to deal with. If you think that you have Raynaud phenomenon, speak with your health care provider about your treatment options.
What is Raynaud's Phenomenon?
Raynaud's phenomenon is a disorder of the circulatory system that causes numbness, tingling, and discoloration of the fingers and toes. Often brought on by exposure to cold weather or intense emotional stress, Raynaud's attacks (also called vasospasms) leave the sufferer with a lack of feeling in the affected area.
Generally, Raynaud's disease is not serious, however, prolonged attacks can leave the sufferer with severe tissue damage, skin ulcerations, and even gangrene.
Between 5% and 10% of the American population is thought to be affected by Raynaud's syndrome. More women than men tend to suffer from the disorder, and it usually onsets between the ages of 15 and 40.
It is estimated that between 30% and 50% of people with fibromyalgia symptoms experience Raynaud's phenomenon too. Raynaud's disease often exacerbates the pain symptoms of fibromyalgia, so sufferers should consult their health care practitioner for treatment advice.
Types of Raynaud's Phenomenon
There are two main types of Raynaud's disease:
- Primary Raynaud's Phenomenon: This form of the disease occurs on its own, and is not caused by an underlying connective tissue disease. This type of Raynaud's appears much more commonly and tends to be mild. It is usually caused by repetitive muscle strain due to activities like typing or playing the piano.
- Secondary Raynaud's Phenomenon: Secondary Raynaud's is a much more serious disorder that tends to have greater side effects. It is caused by a connective tissue or muscle disease, such as lupus, scleroderma, or fibromyalgia syndrome. Secondary Raynaud's is also associated with greater complications than Primary Raynaud's disorder.
What Happens During a Raynaud's Attack?
Raynaud's phenomenon occurs randomly, in the form of attacks. These attacks can last anywhere from a few minutes to a few hours, depending upon the severity of your illness.
When your body senses that it is cold, it will try to preserve heat by constricting the surface blood vessels in your hands and feet. A complex system of nerves and muscles is involved in controlling this process.
People with Raynaud's syndrome have a control system that is oversensitive, causing extreme narrowing, and even the collapse, of some of these blood vessels. They also suffer from spasms in their blood vessels, which prevent blood from flowing to the extremities.
