Wife fell off step in kitchen and banged left rib cage on counter. Pain has increased for a couple of days. Trouble breathing, especially for deep breaths. Hurts when coughing, sneezing, and trouble bending over or sitting up. Noted nausea two days after; not serious, but noticeable. If ribs are bruised or broken, do these symptoms warrant a visit to a doctor? Or, is this a normal progression and give it a few days to see if it improves.
