Hi doctor ! I had kneecap dislocation and was put in plaster for a month following physio. The leg is 90 Percent back to normal. It feels a little weak but ig it will improve with exercises. Mu concern is my knee is still swollen to the size of a cricket ball even when I have started normal movements but its only swollen I don't have any pain. The injury was 3 months ago(plaster was for 1 month and 2 month physio). . Should I be worried and will this swelling go automatically or needs any treatment. Thanks for reading !
