Once, two years ago, was a quick dislocation of the
kneecap - out and immediately back in - with some bruising of the bones. Last year I stretched an attachment of my MCL (?). My knee still hurts almost constantly. The pain moves around and is mainly around the medial, anterior, and lateral portions of the knee as well as directly on the kneecap. Every so often while walking I experience sharp and intense, but very short-lived bursts of pain on the lateral side of my knee.
