Hello
Welcome to health care magic.
Pain in right leg may be due to
osteoarthritis of knee itself or if the intensity of pain is more throughout leg it may be because of pinched nerve due to osteoarthritis of spine.
Meloxicam is NSAID will help you recover from pain temporarily.
If I were your treating doctor,I would recommend,
-You will need to visit orthopaedician for proper physical examination to assess the cause of condition.Investigation like MRI spine will be needed.
-Analgesics like
acetaminophen or ibuprofen twice a day for couple of days.
-Muscles strengthening exercises of back and leg with consultation of physiotherapist.That will you get relief from pain and weakness.
-
Muscle relaxant drugs can be tried for relief of muscle spasm and pain.
-For severe non responding pain to medical measure,option of local
steroidal injection can be considered.
Hope I answered your query.
Wish you good health
