I was recently ill with a common virus I suspect, no fever but lots of sinus mucas which caused lots of coughing at night and waking to expel mucas, sometimes quite violently due to the gagging effect it had on me while trying to clear my sinus, throat and chest. After 10 days I'm pretty much on the mend. However, several days ago I noticed almost bruised like pain in the lower center of my chest and under my left breast a slight distance. Its not a deep pain, almost surface or muscular; Its painful to the touch and on large stretching breaths. Does this sound like costochronditus (sp)? or should I be worried? is there anything I can do to expedite healing. Feels
