I was putting my two year old in his crib and heard a loud pop, felt a really sharp pain through my ribs and it almost felt like it popped out, my back hurt the next day doing anything but was still able to work and sleep, it is tender and painful though, went to store today and started feeling pain through my right side, abdomen and back, when I got home I layed on my back and put my arms over my head and heard a loud pop again, I did feel some relief from it, is it possible my rib was dislocated and just popped back in, and if so should I still see a doctor or just do home care, I feel okay I guess just a little painful now but not excurciating, also I ve had a punctured lung and it doesn t feel like that, should I be concerned?
