i'm 17 years old, and i have been a smoker since i was maybe 13 years old. Lately, especcially while smoking, i've had sharp kinds of pains in mainly my lungs while i smoke, and sometimes im worried it might be my heart as well that hurts while smoking. I know i run the risk of cancer as long as i smoke, and i have already made the decision to quit (for my second time) right after this pack is finished (i literally have about 3 smokes left.. so that will be soon) The last time i quit smoking, was maybe a month or so ago, and i was doing okay until something really personal happened in my family. Then i relapsed, and started again.

I sometimes feel the pain while im not smoking as well, but it isnt as severe as when i am smoking.

-I'm not throwing up
-I don't have pains in my shoulders whatsoever
-And i'm not coughing (although i just got over bronchitis, or mono last month)

So could this be some sort of lung disease? I thought maybe, except for the fact that i figured i would be coughing if it was.

Should i go to a doctor?
Or does anyone have Any advice? or do you think i should just wait it out after i quit smoking for a few days, and see how i feel?

I don't know if this really matters at all either, but i do frequently smoke cannabis as well. But i've never experienced any pains, or anything odd while smoking it at all.

Thanks in advance!
