I really thought I had blown out my Achilles tendon back on Feb 14. I was in the middle of my backswing when the back of my lower leg popped. So after a month off, and two doctors visits, I have made it back on the lanes. Did I get lucky -- YES.  I now wear a compression sock when I bowl. My leg feels fine. But I still have that worry of "will it happen again?" I hope not. But it's in the back of my mind.
