I have pain in both knees, . no swelling, no redness, have suffered no injuries. painful to stand from seated position. squatting is impossible.

Painful knees: You will need to see a physician and possibly have x-rays done of your knees or other investigations to reach a diagnosis, but it sounds as though you could be developing some arthritis. Are you overweight and/or did you play football, especially at an offensive or defensive line position? Either of these could cause significant stress on your knee joints.
