Hey I want to shorten this paragraph out which tells what Raynaud's is, can anyone please simplify it and make it shorter thanks?
Raynaud's disease occurs when the small arteries (arterioles) that serve the fingers, toes, ears, or nose go into spasm. When arterioles go into spasm, they cut off blood supply and cause digits (fingers and toes) or the tips of the ears or nose to turn white or blue and lose feeling.
