Hi all, im not used to any chest pain, until that evening i was smoking and i felt like my heart is gonna stop with some dizziness and serious pain the left chest (the exact symptoms of a panic attack), it lasted for ten minutes and since then the intensity of the pain reduced but did not dissappear i still feel uncomfortable in my left chest, and sometimes the pain increases for some minutes with some dizziness and then go back to the previous low intensity pain. i went to the emergency then to my doctor he did an ECG to me and an echo on my chest and told me that its only cuz of stress and anxiety and what that its a pannic attack that i went through. and gave me sedatif pc and gelsemium as meds. personally idk if this is panic attack or not im afraid its a heart attack. ik that im being really depressed and im through painful moments but im used to it. Can it explode like this all of a sudden? also i smoke weed its been one year now and iv been smoking very frequently this last month , same goes for alcohol. my age is 20 and i don't have any other diseases. And now it been one week since i have this left chest pain and it didnt dissappear but only increases sometimes and i have the symptoms of a pannic attack. i say symptoms of a panic because im not sure yet if it is really a pannic attack . so what is this im really confused. thanks.
