Raynaud’s disease is a type of disorder that affects the small blood vessels. It causes a problem with the vessels in the extremities, and it results in reduced blood flow. When you’re exposed to cold temperatures, the blood vessels start to spasm. This causes tingling, numbness, throbbing or even pain. Such responses may also come from emotional distress. Typically, the fingers are the most affected by the disease. But you may also feel the symptoms in your toes, ears, and other extremities. Usually, the fingers turn blue, white or both within minutes of exposure to cold. Then when you warm up, they become red. The unusual color change is a distinct symptom of the condition. Here are some FAQs about Raynaud’s Disease.

1. What are the major types of Raynaud’s disease?

There are two major types of Raynaud’s disease, and the common type is Primary Raynaud’s. It isn’t usually associated with an underlying condition. There’s no specific cause for this condition to occur. This type isn’t disabling, but it can cause severe discomfort and pain. Because of this, you may need to make some lifestyle adjustments. The other type is Secondary Raynaud’s, and this one is usually linked to another medical condition. Often, it occurs with scleroderma, rheumatoid arthritis, lupus, and other similar diseases. Those suffering from this type may experience more severe issues such as skin ulcers and gangrene.
