I've always had a knee problem it is like i can't sit on them or more likely i can't squat and when i pend them both knees makes voices ! thanks

Knee pain: Pain the knee can be due to tendonitis, plica, cartilage wear, synovitis, weakness, vitamin deficiency. Just too many possibilities without a proper diagnosis. If your knee hurts, start with a basic exercise program for your hips and knees and if your pain persists, or if you feel like the knee is giving out then i would see your orthopedist.
