Thanks for writing in.
If your pain gets better with Motrin
or warm compresses, I think you can wait it out. Unless you have been indulging in some vigorous activity, I dont think you need to worry. If the pain persists for > 1 week, it would be better to call your physician.
However, if you have fever
, breathlessness or cough, we could be looking at an entirely different set of causes. These would be heart disease
which need to be ruled out by a history, examination and some tests.
Hope this helps
