[|AI|]  Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have knee swelling and difficulty to walk after an injury. Well there can be many reasons for symptoms you mention in query like torn ligament (anterior cruciate ligament) , meniscus tear, broken bones, infection or bursitis. I would suggest you to consult orthopedic surgeon for proper examination. Doctor may order CT scan, MRI or physical examination. Doctor may prescribe muscle relaxant, anti-inflammatory along with vitamin supplement for quick recovery. Doctor may give plaster or braces. For now apply ice for 48 hours and warm compresses after that, take proper rest and take ibuprofen or acetaminophen for pain.  Hope your concern has been resolved. Get Well Soon. Best Wishes,
