 [ Symptoms ] i am 20 i smoke 2 to 10 cigarettes daily do not 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 am fixing almost everything especially sleep cycles and diet something i have never thought about was tobacco tho an uncle of mine died recently cancer and i have become a bit paranoid since in the last 2 weeks sometimes i feel pain on my chest it is not specific and it never has the same intensity sometimes it is at the center of my chest sometimes on left or right it is never intense what should i do [ Disease ] 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 have never experienced them since i am not a doctor though so i can not say that you are experiencing the same thing as me but it certainly sounds similar
