I have a sharp pain in upper back when taking a deep breath for about a year or more?

To figure out pain..: To figure out pain that happens only with deep breaths, one has to write down on a big calendar: when it happens, exactly what happens, what makes it worse, what makes it better, what food/drink/meds he took that day, what activities/sports he did that day, etc... Take the diary to the dr. With 3 weeks of data for evaluation. It could be the pleura (the lining), ribs, spine, nearby nerves, etc...
