What is Raynaud’s syndrome, how can Raynaud’s be treated, and what exactly is the relationship between Raynaud’s and fibromyalgia?
You know that feeling when you wake up after having slept on your hand in a weird way? You know that numb, sort of tingling sensation? The one where your fingers look like they’ve been drained of blood? Well, that’s essentially what the syndrome is. But whereas that phenomenon is usually caused by something (like your body) restricting the flow of blood into the affected limb, in Raynaud’s the body seems to trigger this reaction unnecessarily.
Raynaud’s seems to be a result of over-sensitive nerves that respond to normal triggers too easily and dilating your blood vessels, limiting the flow of blood.
One of the most common things that trigger Raynaud’s is exposure to cold. Cold temperatures often cause your body to restrict the flow of blood to your extremities in order to keep your vital organs supplied with warmth. But in Raynaud’s syndrome, this happens after a very limited exposure to cold and can last far longer than it normally should.
This can make Raynaud’s dangerous. As you probably know, your skin needs a constant flow of blood to feed its cells. When the flow of blood is cut off, as it is in an episode Raynaud’s, the tissue can begin dying. This results in painful sores or even gangrene if the attack goes on long enough. See more…
