On the inside of my left knee hurts 24/7. It hurts when I sleep, it swells when I use it. It is completely ruining the quality of my life. I have had this happen before and it takes a long time to heal. Ace bandages make it hurt worse, Climbing ladders or lifting heavy things cripples me. What could it be. Also it seems to hurt horizontally below knee from middle of knee to right inner side. the knee swells on right inner side only.
