Suggest Treatment For Raynaud's Syndrome In A Child

Question: My 11 year old son was just diagnosed with Raynaud's. Right now our doctor is trying to determine if it is primary or secondary. Our doctor is on Vacation until the 30th. His Sed Rate was 15 with normal 0-10. I received a phone call on Friday that his ANA was positive, his RF was negative the only other lab result that was off was his Albumin at 4.9 (ref range 3.1-4.8). When he is cold or stressed all of his fingers go pure white and can take up to an hour or more before they change to red. When his fingers are white he cries with pain. We do all that we can to keep him bundled up and warm. He is always cold especially his feet. He is very small for his age at 58.8 pounds and 53 inches. He eats like no other. He has only gained 4 ounces in the past year. With the above labs should I be concerned that he could have secondary Raynaud's? The only medication he takes is OTC Lactaid, a gummy vitamin and OTC Claritin prn. I should add that when pregnant with our daughter I did test positive for the Lupus Anticoagulant Antibody. Would this be in any way a contributing factor?

He is also complaining of severe pain when his hands are red prior to turning white, when his hands are white he says they tingle like when your foot or hand is asleep. He also complains of pain all the time in his fingers, wrists, ankles and toes. I have attached the labs.
