Back Pain Not From Golf

Well it's hard to believe it but I've hurt my back and no it's not from golfing to much (I wish). I've been off doing the vacation thing with the family and while camping I bent down to pick up my little son in his portable crib and bam I tweaked a muscle in my lower back. There was no heavy crib bedding or heavy toys in his crib he's just a big 7 month old and I've got a 40 year old back. Not a great combo, hopefully it will heal so I can get back out there just when I was starting to see some resemblance of a golf game.
