I have been having knee pain for last one month. It goes on and off. Also, for some days I felt pain in my foot near the ankle but it is fine now. I play, walk a lot in my daily routine. But right now, my knee starts to pain. Pain is sometimes at the outer sides of knee which restricts knee movement, sometimes i feel pain somewhere inside my knee when I stand for some time without moving or play continuously for sometime. Sometimes I feel pain in folding my knee and cant sit in a folded leg position. Sometimes pain is in the thighs also. Sometime back, I was told that I have tennis elbow problem because I was having pain and swelling in my elbow, right now its ok but i think not as ok as it should be.
