i dont know if i have ever had a collasped lung, but after reading this i think i may have. a little less than 2 weeks ago i was having really sharp pain on my side. it hurt to breath and especially to cough. this went on for about a week and a half and now i'm fine, i thought it was a pulled muscle or something. i was having a hard time breathing during this. does this sound like a collasped lung?
