Hi All, I'm wonder if it's ...natural to get a mild discomfort in a knee (right above the hard bone joint and felt inside) when you play 2-5 hours/day, 3 or 4 days/week. I certainly don't want this to get worse because i can feel the worse form of this is definitely gonna cause me to drop playing. Now, can you guys tell me if anything I can do to heal and prevent this? I can only think of playing less and maybe more exercise (but what if this is just inevitable wear and tear so exercise will not help)?? I'm taking glucosamine pills daily but who knows what with it. Thanks.
