I'm 70 and have had it (raynauds) for long time too. if u can tolerate a med that lowers ur BP, a calcium channel blockers like my new PCP gave me may help u too. was already on Lisinopril for BP, so he just changed my BP med to ccb. has "desired side effect" of helping with raynauds! mine had gotten really bad, and this been life changer! can make it 2 car in super cold weather , etc ice tray outta freezer, etc, without attack!!!
