Hello, Looking at your age it looks like you may be suffering from arthritis of knee. There are also various other reason for knee pain. I shall advise you following to have relief: - Avoid frequent up or down on stairs - Avoid cross leg positions - Start doing some exercises like quadriceps strengthening exercises - Take a mild analgesic on and off like advil for relief from pain. In severe pain there are some other drugs which can be prescribed but they come under narcotic category and can be availed only on doctor prescription. - Apply a local analgesic ointment and do warm water fomentation with water bag over the knee. - Take some joint supplements like collagen supplements or glucosamine or chondroitin sulphte. If all this does not resolve your problem then you may consult to your doctor and get yourself investigated including X-ray and blood investigation like CBC, blood sugar, thyroid functions, serum uric acid etc. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Mukesh Tiwari, Orthopedic Surgeon
