Hi , I have right sided rib pain under breast area radiading around side of rib cage. Felt a pop in the sterum area when my partner came down on me during intercourse. We shifted position slightly and continued, however I was very protective of my ribs.. He has a much bigger chest wall and heavier than my self. I have a tender spot on the rib on palpation. yesterday was able t take care of two kids 6 months and 4 years old and did fine. This evening has become more painful and having pain on deep breathing. taking ibuprofen and putting heat on the area. Thoughts?
