This probably doesn't count - but it's a little thing that has made my life better today...
I play a LOT of table tennis, and have been hampered lately with shoulder pain that has been gradually getting worse. Not bad enough to make me stop, but enough that I've worried I may have to at some point. Anywho (learned that in an earlier post), tonight I was at the club in a heated match, and I step around my backhand side to hit a crosscourt forehand. My opponent then hits a drop shot on my wide forehand side, and I have to lunge over to get it. I do get there in time, early enough in fact to attempt a down the line kill. Well, I'm so off balance from the extended reach that I hit a terrible stroke, miss the table entirely, and I feel a crunching "pop" in my shoulder, accompanied by a sharp pain.
Oh oh, I think - there is goes. But lo and behold, suddenly my shoulder feels fine. The pain that's been dogging me for several months is entirely gone! Seems I may have somehow freed some sort of impingement.
I'll know for sure in the morning. For now, I'm knocking on everything wood that I see, in the hopes that this miracle isn't temporary. If it still feels good in the morning, I probably should pay my opponent as a thank you for the chiropractic adjustment.
