hi there,
reading all these posts has been helpful - I have a similiar chest pain on my left side that hurts when I stretch or take a deep breath, the left side of my chest is tender when I touch it. It's certainly a concern, and I've been reducing that amount I smoke / inhale - though it hasn't gone away yet.
this pain has been going on for over a week, though I'm familiar with it - it's been coming on and off, depending on how heavily I smoke. I should add, I don't smoke cigarettes, I smoke pot. Over the last couple years, I noticed that the amount I smoke would inflame both my lungs and throat. I was worried, so I went to the doctor and they performed various lung tests and diagnosed mild copd - which, like an earlier post says - sticks with you, and makes your lungs more fragile, I think.
I bought a good vaporizer last fall, and that has helped quite a bit, though I still get worrisome inflamation at times, and it seems overall, my lungs are much more suseptible to irritation - this may be a lasting legacy of copd?
About 2 weeks ago, I turned up the temperature of the vaporizer, I used it for about a week on its highest temperature. (a higher temp produces a denser mist) That, and a couple joints over those two weeks (I really don't smoke joints since getting the vaporizer) - seemed to inflame my lungs.
Now - like I said - I've a tight chest pain that hasn't gotten any better for a while. I've turned down the vap to low levels again, and will keep it there, though this chest pain does hurt, and it is worrisome.
I'm trying to cut back or quit completely until this chest pain subsides, which really may be the only way to know if it's my smoking habits that are doing this, or something else...
I found others posts useful, comforting knowing it's probably related to what I smoke, (and not something worse, at least not yet) - also knowing others are going through similiar worries-
