Hi doctor! History: Patella dislocation 8 months before and now the joint is completely fine. But the one thing that is not going away is the pain. Whenever i touch my Patella or move it it causes sharp pain when I move it towards lateral side. It happens every time even when the knee slightly touches the bed when I sleep on stomach. The swelling has also not gone from when the injury occured. What can be the cause of this pain ? It also pains when I walk downstairs. I don't have the Xray and MRI was not done. Thanks a lot for reading my problem sir ! Pls tell
