Purple feet, red hands, pain in knees

My daughter who is now 20 has been seen by several Dr.'s for these symptoms. They have ruled out Reynauds (Which the Dr. thought for sure it was) they have ruled out autoimune disorders.Her arterial doppler ultrasound showed weak pulse in two areas. So the internal Medicine doctor who ordered the tests said go see a Heart Dr.. We made an appointment and That Dr. and he said sorry I don't deal with this problem and had no advice for us on who to see. It has been 2 years now and My Daughter is worse off. She has developed pain in her legs especially in her knees. she complains of pain mostly behind her knees. She has an appointment to see a knee specialist. She relieves the redness , pain and swelling in her hands by raising her arms. Her feet turn purple, but her pain in the lower extremdies are in her knees and calves. She is frustrated. She has never smoked or drank achohol and is not overwieght. A friend said she might have Atherosclerosis. She can hardly walk for any distance or stand without pain. Any help is appreciated on who to see about this.
