I have a significantly higher blood pressure when taken in my right arm -- 145/99 -- versus 117/75 when taken in my left arm. My right wrist had been very badly broken several years ago in a horseback riding incident. I had surgery on the wrist and it has healed very nicely, although it's a little bit bigger in diameter than my left wrist. I remember the ortho surgeon commenting about my having a good supply when taking the pins out of the wrist. Could that be causing the higher blood pressure reading? I'm 53 years old, very active, not overweight, no other health issues.
