is anyone familiar with this problem, which i think is related to playing guitar?

2)when i bend my knees it really really hurts. i basically cant bend them. when i say bend them i mean the full way. like if i were to do the water sport, kneeboarding, i would be in a lot of pain. and i cant sit on my knees the full way down either.
what is that all about?

and how can i help these problems?
I have the first problem, and I've been told that it just takes some experience. How long have you been playing guitar, and how often do you practice? I only get it when I play power chords for extended periods of time, it seems like keeping my finger positioning in that stance for too long puts stress on a certain part of the joint and it ends up feeling really tense and hurting. I've heard from other people though, that after time and practice this usually fades as your joint will strengthen.

About the second problem, you may just have bad knees, or even arthritis or something. The only thing I can think of to tell you, is that some supplements like calcium or magnesium might be beneficial to you, you may have some sort of a deficiency.
