i am a 20 year old male and have being having some extremley worrying symptoms for a while now. i get a lot af central chest pain that comes and goes all day, sometimes it spreads 2 my left arm neck and back, i get shortness of breath, palpatations, irregulur heart beat and pvcs, i also go light headed an dizzy sometimes and get really hot and sweaty, sometimes pins and needles, but not often. i have been to the a&e numerous times convinced i was having a heart attack, but every time they did the ecg they sed it was fine, they also did another test which is like an ecg but they stick the wires around the heart for a more accurate test and that was fine to, they told me its anxiety and panic disorder, the thing is these symptoms feel so real and are very scarey, i get them more when im resting rather than excersizing, infact i dont usually get them whilst excersizing. i am just wondering if it is anxiety or if there actually is something wrong with my heart or mabey blocked arteries and need some different tests for it to show a problem. looking forward to your feedback, it would really help, thankyou
