<s>[INST] i have a strained ligament in my knee and was wondering if heat would hurt i strained it on friday may 30 i slipped down our steps in the rain and it twisted underneat me a little i have no bruising and minimal swelling after the fall i can put weight on it and walk just when i first stand up its light the ligament is tight and have to stand a few seconds and let it stretch . i can walk on it and put weight on it it jus pulls when i bend that knee to walk not really hurts jus uncomfortable. [/INST] With such presentations in my clinic, I would first rule out the fracture by doing X RAY knee joint and then ill diagnose. If there is no fracture based on clinical examination ill diagnose the cause, and mostly it should be a ligament injury, if so ill go MRI knee joint. If any tear diagnosed then ill suggest for arthroscopic repair.  Kindly consult an orthopedic surgeon regarding this.  Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions.  Wishing you good health. </s>
