Raynaud's Phenomena

My sis seen by the neurologist yesterday and she was diagnosed with Raynauds 'Phenomena. I am worried for her because she's ll be back next month and decided to continue her check up in Canada. I doubt if she can continue medical checkup and have the treatment if there is any because she's always busy with their family business without giving attention of herself. I am worried for her, really she might not continue seeking medical advices again. Her blood examinations for thyroid, kidney, blood sugar are normal but her cholesterol level is obviously high. Echo Cardiography is normal but seen a mild abnormality of the mitral valve. The cardiologist wanted her to see the Rheumatologist for her Reynauld Phenomena for further evaluation and management but she refuses already . Still she's having the bluish discoloration of her fingers and toes. I wanted her to stay more here to continue check up for the final diagnosis and she may start the treatment whether here or in Canada. I wish that she is completely well before going back home. I am ready to help her all the way.
How i wish and pray that her raynaud's phenomena is just only primary that will disappear soon specially the symptoms she's having now. Comparing the pictures in Wikipedia are severe cases but thank God , my sister is just a slight symptoms that's the reason why i wanted to be treated as soon as possible but she refuse and in a hurry to go back home.

( According to Wikipedia )Raynauds Phenomena in medicine, is a vasospastic disorder causing discoloration of the fingers, toes, and occasionally other extremities. This condition can also cause nails to become brittle with longitudinal ridges. Named for French physician Maurice Raynaud (1834 - 1881), the cause of the phenomenon is believed to be the result of vasospasms that decrease blood supply to the respective regions. Emotional stress and cold are classic triggers of the phenomenon, and the discoloration follows a characteristic pattern in time: white, blue and red.
Primary Raynaud phenomenon, stemming from Raynaud disease, is an exaggeration of vasomotor responses to cold or emotional stress. More specifically, it is a hyperactivation of the sympathetic system causing extreme vasoconstriction of the peripheral blood vessels, leading to tissue hypoxia. Chronic, recurrent cases of Raynaud phenomenon can result in atrophy of the skin, subcutaneous tissues, and muscle. It can also rarely cause ulceration and ischemic gangren
