<s>[INST] I have a constant pain in my right lower leg from the knee down. My only relief is a heating pad at night. I am a Type II Diabetic. What could be causing this and what treatment for pain could I use? I see my physician Aug. 30th. My email is: YYYY@YYYY [/INST] Dear patient you might be having knee osteoarthritis. Pain usually is located to the knee but may be going down the leg. I would advise xray of involved knee with leg anteroposterior and lateral views to confirm Diagnosis.Please get it done from radiology centre nearby you. Meanwhile start tab diclofenac sodium 50 mg twice a day for pain relief. Local application of dynapar gel helps in pain relief.  Avoid squatting and crossed leg sitting.if Xray is abnormal please consult orthopaedic surgeon nearby your area. </s>
