I have been diagnosed with raynauds and was given cialis to take to help blood circulation. Though the cialis did help slightly it gave me bad chest pains like something was sitting on my chest. So now I just thaw out in warm water every evening and sometimes during the day if I'm able to. I try to always have a blanket, jacket whenever I go somewhere that might be cold. I also wear a beanie almost everyday. My raynauds seems to be worse when I take my meds for a prolactinoma.
