I've never had knee problems all my life, only until recently when I started playing volleyball again. Ever since I'm noticing irritation right below my knee caps and even for a few days after playing volleyball.
I'm in my early 30's but never thought I would end up like those guys you see that need to wear a knee brace when doing any physical activity. I'm hoping this is just a phase that will eventually go away. The sad part is that I only play once a week too so its not like I'm overtraining it :(
