With reynauds can it affect internal organs?

NO: Most patients with raynauds have symptoms of the hands, feet, and rarely the nose and even more rarely the nipples. We typically do not see raynauds affect internal organs.

Sometimes yes: While raynaud's is seen in the hands, feet, nose and it is related to muscle contraction in the vessels in these areas. The blood vessels have muscle around them and like the heart these muscles have a rhythm of contraction and relaxation. With cold or stess these vessels can contract and decrease the blood flow in these areas. Internal raynaud's can occur in the heart and the kidneys!
