Ive been having chest pains and the feeling of my heart skipping a beat or sometimes fluttering for about 3 months now along with dizziness and head/neck throbbing when i stand and some nausea ive been to the hospital several times with no results thus far only that i had high blood pressure and some kidney thing on meds for the high blood pressure and going back for a biopsy on my kidneys but I dont think those 2 things could be causing these problems anyone out there have any idea what this could be or have the same symptoms im only 19 I shouldnt have these kinds on problems this early in my life
