This is an excellent post and makes us all wonder...I have been having a huge problem with high blood pressure and it has made me think about everything I eat, because I have to certainly have to watch my salt intake. I have recently learned that high BP goes hand in hand with RSD and my doctor informed me that if I didn't get my yo yoing BP under control I would certainly have a stroke...he stated that he attributes my BP issues on RSD, so in some ways I feel that RSD can cause someone to die.
