### input:
I m a runner. I ve never had issues with knees. Two weeks ago, I ran 8 miles (which is less than my normal), and was fine, until I rested. I limp when I first stand up - about 5 steps, and then I can walk normally. I rested it for 3-weeks, besides my normal work schedule and I iced it. I went for a 3-mile run today. I m limping again about 5-steps and then I can walk normally.

### output:

Hi, thank you for providing the brief history of you. A thorough musculoskeletal assessment is advised. As mentioned by you about the limping, I will recommend undergoing a complete clinical Musculoskeletal assessment as some clinical orthopedic special test will be performed to check the status of the soft tissues within the knee joint. Usually this limping occurs due to locking of the knee joint as by which the knee does not become flexible to move around. Runners usually suffers with ligament injuries over a period of time and needs a thorough assessment. Also post the clinical assessment may be an MRI of the knee will be guided to check any soft tissue Injury. Which is important to know right now itself to avoid the latter coming days' injury. With rest and physical therapy the knee joint mechanism will be achieved. Also, on later stages a sports retraining program will be implemented by which the becomes stronger to avoid pain and aches along with locking unlocking mechanism to function to the optimum. In my clinical practice I have seen cases with sucChatDoctorplaints and by a thorough detailed clinical assessment and use of MRI helps us to help the patient further for the best outcome score. My patients even achieved 100% of the score in their knee mechanism. I expect the same from you.regards Jay In Chat Doctor.
