For my entire life I've actually noticed this but never gave it much thought as it was quite infrequent... the last 10 months it's gradually worsened. It would always be the right arm. The last 6 months it will spread to the left and cause shortness of breath of I just keep going and ignore it.
I've had a calcium CT scan done with a 256 slice scanner which showed a score of "1" .. I'm 32 and my cholesterol and triglicerides have always been excellent ( 69 HDL, 65 LDL, 50 TRIG) ... My blood pressure when tested manually by doctors tends to be around 118/70 and when tested with automated machines is more like 130/85 for whatever reason. Every time. My heart rate gets really high easily while exercising, which the doctor who did my stress echo noted (up to 175+ bpm) but wasn't that concerned about. My blood pressure during this test didn't seem to bother him. My heart rate recovery was good, and he described my heart as well conditioned.
The stress echo showed "moderate aortic insufficiency with no stenosis" and a biscupid aortic valve.. the regurgitation did not worsen with exertion, it was steady and consistent. He said he wanted to see me again in "under a year" for another echo.
Could this pain be caused by high blood pressure? It seems worse during times when I am anxious, and I have had anxiety because I have had these symptoms gradually worsen and I've always been into cardio. A vicious cycle of sorts. Could the regurgitation be causing symptoms? I notice I don't tolerate weight lifting well and will get various symptoms days afterward and the bounding pulse will get worse afterwards.
