Hi, you are on supportive medications. Etoricoxib
is for pain, Glucosamine
to improve your cartilage. From that I gather that you are developing arthritis
of the knees. The medicines are good and prescribed to help you, but I wouldn't recommend Etoricoxib for long term treatment. You will benefit from hot and cold compress, elastic knee support, Physiotherapy
modalities like Diathermy and Ultrasonic and a thorough assessment by your Orthopaedician as to the severity of arthritis.
