I was getting bad pains where I couldn't take in full breaths when I was smoking a lot (like 2-3 times a day, lol)
They randomly vanished, I still smoke but only on weekends now but that's more of a money problem

I know a few smokers that this happens to, this was happening to me every 5 to 10 minutes a month ago and couldn't find any answer to it online. They come and go I guess, some people have told me it could be collapsed lungs since I'm tall but it went away on its own.
