i used to smoke a similar amount and would often get pains in my chest on a morning sometimes lasting for a couple of hours. i used to worry about them quite a lot so i quit smoking to see if it would relieve them. the first couple of weeks after quitting the pains got worse but then stopped completely. i've never experienced them since. i'm not a doctor though so i can't say that you are experiencing the same thing as me. but it certainly sounds similar
i'm 20 i smoke 2 to 10 cigarettes daily don't exercise eat unhealthy stuff and feel sometimes pain on my chest. my lifestyle is anything but healthy (but thanks to my duties on university i'm fixing almost everything especially sleep-cycles and diet). something i've never thought about was tobacco tho. an uncle of mine died recently (cancer) and i've become a bit paranoid since in the last 2 weeks sometimes i feel pain on my chest. it's not specific and it never has the same intensity (sometimes it's at the ''center'' of my chest sometimes on ''left'' or ''right''). it's never intense. what should i do?
