I felt foolish for going to the emergency room but I couldn't go on any longer without knowing how to get relief. You see, I went for a bike ride - because I felt totally fine - and when I got back I coughed a little which caused the end-all pain for me.
It hurt to move, bend, use my arm and breathe. Breathing is not supposed to hurt. So in addition to the elastic brace, they gave me some muscle relaxers and authorized me to use the Vicodin from my surgery. I've barely taken anything since I don't want to be loopy.
In the meantime, I've become quite aware at how much I use my "core" muscles, including my oblique muscle in everyday life. It makes me want to do Pilates or something when I'm done healing. Either that or eat more donettes*.
*donettes are those little powdered donuts that you get from Hostess.
