Hi guys, I'm new to this message board and I'm really trying to find help.. Here's my problem, whenever I sit down for a long or semi-long period of time, my knees start to feel weird.. it doesnt hurt.. but they feel uncomfortable.. they almost feel warm when I touch them. I'm only 19 years old so I don't think it could be really anything serious from too much stress or weight problems.. my mom said it could just be from lack of movement and my knees just arent used to it? Anybody have any ideas or know any sites that could help? Thanks for your time and sorry if this isn't the correct message board to pose this question.
