<s>[INST] I am 57 yrs old and I was climbing down off ladder and lost my balance and missed the last step on the ladder and landed on the hard floor with all my weight on my right knee I heard a loud pop but i still walked on it for about 2 hours then it hurt to bad to keep walking. I was a doctor at a clinic and she put me on light rest walking 2 hours a day. My knee is still hurting and it has been 4 weeks now. What do I do? [/INST] hi,thank-you for providing the brief history of you.A thorough musculoskeletal assessment is advised.As I gone through the history I feel you should consult a orthopedic and get the knee assessed. As the pain is still not reduced. Also, by understanding your mechanism of injury I feel you must have injured your ligament. As you are 57, the  degenerative changes in the knee must have been present and can damage any soft tissue with smallest or hardest impact.Also, your ortho may recommend you an MRI of knee to see the soft tissues within the joint.Post which the treatment will be planned. With proper medication and a combination of physical therapy you will have better strength and your mobility will also improve.in my clinical practice such cases of ligament injuries are always delayed to undergo physical therapy and the recovery time is delayed. So I advice you to take up at the earliest and make a rehabilitation process start soon.RegardsJay Indravadan Patel </s>
