You should see a doctor.
Were you recently involved in an accident of sort? It could be a broken rib(s). If not, and depending on your age it could be a number of things. If you are older, usually over 45, you could be having angina or heart problems.
If you are sweating and nauseous, call 911.
Sounds like you could have pleurisy, have you had a cold recently? Google it and see if this sounds like what you have going on.
After I gave birth, I had really sharp pain in my shoulder when breathing. I was told it was an air bubble that got trapped in my body. (Somehow?) It hurt like hell, but went away after a while.
Don't know what yours could be. Did you hurt yourself in anyway?
