40 year old female. I'm looking for the best treatment for Primary Raynaud's. Live in harsh, cold environment take 360mg of Gingko/day but no other medication/therapy for this disorder. Besides Raynaud's, I have Iron Deficiency Anemia caused by Malabsorbtion Disorder and receive Iron Infusions weekly. Have normal to low Blood Pressure and take nexium for acid reflux.

Summarized question: Which is the best treatment for primary Raynaud's?
