Yeah, I got one. It was huge at first, about 3 - 4 finger widths. It is closed now, and I havent exactly made any effort to work on it so I guess it can just fix itself on its own. I cant remember when it went back together, but it did take at least 6 months. But as I said, I did no special exercises to help it along, so maybe if youre doing appropriate exercises it would be quicker.
