I am having pain in the upper chest of the left side in the underarm  region which radiates sometimes to left hand back left shoulder and right chest . I also feel fast pulse in my neck . Sometimes there is also pain in left jaw. In my blood test there is high level of lpa (30-40) and low hdl and normal ldl. I went to cardiologist and my ecg tropinin i and stress echo  were normal twice . Is my pain cardiac related or is it because I am not getting enough sleep
