Did you have an exercise echo to exclude a cardiac cause? Is your blood pressure equal in both arms? Did you have a CT scan to exclude a herniated disc or an emg to exclude a pinched nerve?
I just wanted to let you know that I had the same symptoms and also thought it was heart related. In fact the cardiologist I saw thought perhaps it was coronary artery spasms and put me on low-dose norvasc for it. However it did nothing to relieve my symptoms. Finally he ordered a HIDA scan which revealed that my gallbladder was not functioning properly. I did not have gallstones. I had my gallbladder removed and the symptoms completely disappeared. If your heart tests show that everything is OK there, you might want to talk to your doctor about a HIDA scan for the gallbladder, NOT JUST an ultrasound which only shows gallstones.
Thanks for your reply. What are you going to the chiro for?
