I have pieced together how the heck I hurt myself.....mind you, it is not too hard to do that. On 9-15 we had our company outing. I purposely strayed away from the batting cages for fear I'd tweak my shoulder (my old swimming injury). I played 9 hole, pitch and putt and then gave in and went to the batting cages deciding the shoulder could not get that bad. Well, it was the hammy to watch out for....D'oh!! I am such an idiot and as fragile as a flower. Live and learn.
I ran 4 miles last week (2 miles per day) after 4 days off and then needed another two days off. Time will tell.
