text: pain underneath my right shoulder, pain while breathing deeply and yawning? i've tried doing research on this to pinpoint some sort of at-home treatment to prevent seeing the doctor (can't afford right now). basically, i have a constant degree of pain below my right shoulder that i've never had before. the only thing i really can see that caused it was some stretching, but that isn't out the of ordinary. its been pretty constant now for 3 days and even hurts when i inhale deeply or yawn.   anyone out there expieriencing this too? any recommendations for treatment. currrently i'm taking 8-hour tylenol.  thank you! if we're trying to think on most positive terms it could just be a muscle pull.  there are some gels that might help, but what is your age? i would suggest that the best thing to do would be to see a doctor to rule out other serious causes. sorry.
