I had a similar problem last year. I also had upper back and neck pain so doctor sent me to physical therapy. Turns out that I had an intracostal muscle in spasm. I never even knew that there were muscles between the ribs. The therapist discovered the problem by sticking his finger between all my ribs. I hope your problem turns out to be as simple.
well i no that coughing a lot and hard can do that, but i dont cough that hard. and no injuries or anything. 14 yrs old. Nothing that I can think of. it might just be cartilige rubbing or something. makes it hurt once in a while.
14 is pretty young. i forget to what age exactly, but in kids bones and joints look different than in adults.
for example, to identify a possible fracture in a kid. ud have to take xrays of left and right (arm for example) to compare the way the bones look, to identify abnormalities.
anyway what im trying to say. wat you have might just be age related and the fact that ur growin and ur body is adjusting.
but if its bothering u a lot. you can go see an ortho doctor and take a simple xray.
good luck
any recent injuries? car accidents? slip and fall?
age?
