Hello! My husband has been diagnosed with Raynaud s. Along with the extreme sensitivity to cold he starts to sweat mainly along his neck and the trunk area. Once he gets the cold sweats he is not able to warm up until he gets into a warm shower. He has had tests for lupus and other diseases which were negative. So the doctor thinks it is primary Raynaud s as opposed to secondary. I have read online information from Dr. Weil but want another doctor s advice too. My husband bp meds have been changed to a calcium channel blocker blood pressure med and Ginko Biloba ( for about a year) and the symptoms. are not being relieved.
