[/INST] Hello, In the present instance if you are feeling this pain first time, then most probably, this can be due to strain over your knee. To me at present it doesn't look to be e a a case of osteoarthritis knee. I will advise you following to have relief at your knee pain- 1. You should avoid heavy work. 2. You should take proper rest. 3.  You may take a good analgesic like acetaminophen for  relief from pain. 4. You main apply warm fomentation to get relief from pain. 5. You should also wear a knee cap to support your knee. You may have relief from this knee pain in in next 5 to 7 days. Hope I have answered your query. Let me know if I can assist you further.
