<s>[INST] hi I have been having been suffering with some intermittent knee pain ever since I landed awkwardly as a goalkeeper when in a PE lesson in school I have repeatedly been to the Accident and Emergency department were I live but have repeatedly been turned away saying I have just sprained it ive had a few instances were my knee has frozen and I haven t been able to put weight on it I was just wondering if you could advise me what to do [/INST] Hello, What I can infer from the complaints you have described is that you may be having episodes of a knee. Joint locking. It happens when there is an obstruction to smooth movements of knee joint f on any soft tissue structures in the knee like a meniscus. The best method to diagnose this is to get an MRI scan of the knee joint. It will tell your physician the cause of your knee problem. Hope I have answered your query. Let me know if I can assist you further.   </s>
