Spoiler alert: Not much can be done about it--you just accept it as part of your new normal. But it does mean it is not a serious issue of concern.
+1. I did two emergency room visits for costochondritis. Really scary and annoying, but no real medical harm. Heavier dose motrin for a week or so can make it go away. And be careful with activities that stress the front of the chest, like clutching a steering wheel for a long trip.
