Today started out well enough with me working through my breathing exercises and stretching exercises. I did several round-trips up and down our staircase (14 steps) and was feeling quite good about my physical progress. Then at lunch I choked on some apple juice I was drinking and that sent me into a bit of a tailspin. The coughing that resulted felt like I was tearing things inside. I spent the rest of the afternoon in my recliner with moderate pain in my incision area and in my diaphragm area.
Note to self: Be careful not to inhale liquids so as not to do yourself in again!
