<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor, I have been experiencing severe numbness and tingling in my fingers and toes which turn white and blue when I get cold or stressed. I think I may have Raynaud disease. What medications should I take?  <response>: Based on your symptoms and diagnosis of Raynaud disease, I recommend you take Nifedipine, Mycophenolate Mofetil Cellcept, or Hydroxychloroquine Plaquenil to manage the symptoms.
