hi, i wonder if someone here could help me?
im 25 year old male.
regular height/shape/size.
recently, for a month or so i guess, ill breath in and get a sharp pain which feels like its from my heart. left side of chest, under ribcage.
it tends to happen after ive woken up and am stretching, or sitting still for a while.
anyway, ill breath in and it feels like something will burst. so i have to stop and breath in veeerrryyy slowly. and then normally, after ive inhaled slowly without pain, i can breath again normally, until the next time.
but this is happening 3 or 4 times a day now, and its a little worrying.
if anyone could let me know what it could potentially be, i'd appreciate it. thanks.
i am a smoker, btw.
