I was doing some breathing excercises three nights ago, and I decided to try and inhale as deep as I possibly could. (I used to be a very strong competitive swimmer and almost had no limit to how much I could inhale).
Well, about 3 minutes after I took this “way too much” breath, I got a sharp pain (kinda burning, more like a shot going into your lung), which initially felt like it was SOLELY in my lung.. not my back. (Hint, I know what a pulled muscle and a pinched nerve feel like. This was not that feeling.) I even had my boyfriend rub the area for a while. Now luck.

So then I started getting this pain significantly worse when I inhaled all the way (even normal breathing.) I ended up not sleeping that night because I was restless about my shallow breathing I was having to be conscious about… ‘not crossing the threshold into severe sharp pain’.

The sharp pain I get from regular breathign has subsided, but when I try to take that deep breath again, it can be felt.

My friend says maybe I popped a blood vessel in my lung?

Has anybody else had this happen? Found a cause? Found a cure?

Thanks much!
