Since the beginning of this month I started feeling pain in my left leg joint and it remained continues throughout the day until I sleep as I am not able to stand properly or sit properly due to the pain. In emergency I bought a medicine namely tablet ugesic and I used this medicine once a day for 5 days and felt a little bit of relief but not that much. I want to know what is the problem and how to deal with it at home as you know due to covid, we can't go out so I hope you will give me some solution.
