See orthopedist: There could be many reasons for your symptoms ranging from truamatic or non-traumatic causes. You don't need to have an injury to experience the symptoms you have described. Common causes include early arthritis/wear/tear, ligament injury or meniscus tear. If you are not satisfied with your recovery and if symptoms are unbearable or worsen then see an orthopedic surgeon for clarity in diagnosis.
