Im 15, around 55 and about 7 odd stone. I have no medical history that is anything to worry about. Since last night while in bed I all a sudden after streching got an achy pain in the top-middle area of my rib cage. It hurts when I breath deeply, laugh, sneeze, turn around to my right, sit down and when I lay on the same side. Also, for the past few hours Ive come over dizzy aswell as still having the pain in my ribs, especially when I lay down as the room feels slightly as if it is spinning. Every now and then this gets worse for a few minutes..
Hey there, It might be just simple muscle sprain, but I would still advice you to go for chest x-ray to rule out any cause related to lung.
