Question
I've been sick for a few days and have been coughing very hard. Today I was standing in my room and I yawned and my back tightened up and i couldn't breathe. I went and got a massage thinking it might have just been a muscle. It's on an area on the back of my ribs. I have a hard time breathing and doing anything but laying on my back. There is no lump so I'm not sure if it's popped out of place. The lady who gave me the massage told me that I might have popped it out of place. I'm just scared of cracked it but I'm not sure if I could have done that by just yawning. Is there anything I should do ( chiro, or x-rays)? Thank you.

Answer
it sounds like you have subluxatd(misaligned)  a rib. if pain increases when breathing in then thats most likely the problen. i would definitely go see a chiropractor. There was no trauma , therefore x ray is not neccessary. although i say that without knowing your past medical history and that would have to be determined by your chiropractor.
