[|AI|]  Thanks for contacting Chat Doctor. You have problem of knee swelling that may be because of menisci injury. Blood vessels or nerve injury cause pain and swelling around knee area. Take one knee x-ray... Any bony injury can detect by this. Muscle or tendon injury may cause pain and bruising... Treatment plan depend on site and stage of injury. Take a rest. Avoid excessive straining of knee joint. Consent a physician for further diagnosis. I hope my diagnosis is helpful to you. Take care. Thanks.
