The first workout in a long time where there was no serious pain on my left side or anywhere else. Maybe I am healing? Am sore now (a few hours later), but that is typical and not where I had feeling soreness before. The important difference is that during my treadmill run I felt OK! Today I managed to walk/run for 4.25 miles with 3.35 miles of continuous running. For the next week I will continue to take it easy and hopefully I will observe similar pain free running sessions. I was beginning to lose all hope that my discomforts would ever disappear.
