Snap Bobert same thing happened to me today, I went see the bone man and he tugged me about for a bit, it was my left hip that causing the trouble, got to go back to see him again tomorrow, says its going to be a long fight - but as you know I'm used to those - wish you well with yours its not a thing you'd wish on your worst enemy.
By the bye Bobert heard your CD the other day - you're one hell of a good performer.
