Health question,For the past 3 days I've had a sharp-ish (not too bad, just uncomfortable) pain in my chest (on the top where my right breast starts and towards the center, doesn't radiate to the back) when I breathe in deeply at the very end of the inhale. Sometimes there's a creaking noise with it too (but not that often). Any idea what this is?
Also, I'm 21 and have been smoking for a year (pack a day).
It takes decades for smoking to cause cancer, you're just feeling self-conscious. I feel random pains like this every once and a while, it could be because of anything from bad posture to sleeping the wrong way.
You probably pulled a muscle and your bones are creaky. Sheesh.
