Golf Tips: Golf Swing Gone Bad Any Tips? (5/15/2012)

I’m at 18 handicap and something happened the last two weeks and I can’t even hit the ball. I’ve hit the range many times and can’t figure it out. Every time I hit the ball regardless if im hitting dirt the club turns in my hand so the club head is know more closed. I tried bring the club back more inside which has helped some but really frustrated. Have tournament tomorrow and have been shooting in the 110-117 lately. I hurt my back don’t know if that is a problem?
