I couldn't think of a decent title. That being said, I had an odd occurence this weekend. My shoulder was OK, not great, but OK Friday. I hit around vigorously Saturday (no serving) and it hurt like mad afterwards and the remainder of the day. Woke up Sunday and it felt better than it has in months. Any explanations. I simply got a quizzical look from my PT when I told him this (I think he wasn't overly thrilled about me playing but oh well).
