my husband seems to have displaced some ribs on the left side, they feel out of place, he had bypass surgery Jan 10 and is in rehab, but decided to so some situps on his own 2 days ago, the pain started as an aching in the rib area about 3 inches below the left nipple and now he is really in pain. I have given him Advil 200 mg. I would like for him to get an xray but he doesn't want to do the ER tonight, any suggestions to keep him comfortable
