Hi im an 18 yr old i weigh 65 kgs and am 6ft 3inchs tall.

a few months ago i snorted a certain substance which you will probably guess. within a few hours i had a strange feeling in the left part of my chest that felt like my heart was having some sort of problem i nearly blacked out and my heart started racing, this may have been a panic attack.

i went to hospital, iv had ecgs or whatever their called and a chest xray.
they say everything is normal.

i suffer from chest pain every day in the left and centre of my chest, my shoulder and underarm.

it is usally triggered by -

-smoking a certain substance begining with c and endng with bis.

-taking a certain drug begining with e and ending with asy

-smoking too many cigarettes

-eating to much food, especially junk food

-thinking about the problem and what it could be, which i find extremly hard not to do when trying to fall asleep or when iv got nothing else on my mind

sometimes alcohol triggers it

the pain is relieved somewhat, sometimes by-

-beltching

holding my left elbow in the air and holding the head of the chair im sat on, or holding the back of my left shoulder.

sometimes the pain is bareable, sometimes it really hurts and i feel sick.

i have taken quite alot of the substance begining with e but rarely snorted any substances and before that event and havnt done since, wel not entirely true but nothing effective.

does anyone have any idea what the problem could be my local doctor always seems to want me out the door saying im fine, but im far from it, i cant enjoy myself anymore because of this problem.

please help
