Not Raynauds: Raynaud's disease is due to spasm of the muscular lining of the blood vessels due to temperature extremes. They will turn blue with cold exposure and red with heat exposure. Standing means the blood is pooling in the veins and the superficial ones will dilate. The legs look blotchy but it is of no concern as this is normal. 18 years old is extremely young to have raynauds.
