Hi, I ve been having pain in both knees for about four years now. I first felt the pain after a tennis match my sophomore year of high school. My left knee bothers me the most. My knee cap often feel uncomfortable and I constantly feel like I have to move it. The doctor I go to now said my knee cap was a little loose. After physical activity of any kind, I can place my hand above my knee cap and I can feel both knees pop. My left knee also feels like it is pulsating and I have seen the side of it move as if it were beating. My knees bother me more when it s raining and cold and my left knee has given out on me before. Growing up, I played basketball and lacrosse and in high school I played tennis almost every day from spring until end of fall. Will this every go away on its own or do I need to see someone specifically for it?
