Hip bone pain in both left and right hip

Dear doctor.. My father was corona positive and was on medications till 23rd may 2021 but now he is good. He is facing pain in hip bone both left and right and finding it difficult to get up and sit down. He has not taken any pain killers for it as he was on medications earlier and was corona positive. This is not a new thing.. This has happened to him in the past also and he took pain killers and homeopathy and got relief. Please suggest if he can take a pain killer as the pain is acute and there is difficulty in sitting and moving. Even if he touches the hip bone it is paining. No injury nothing has happened . There is no previous history of any injury also. Please suggest a pain killer for instant relief. As he was on steroids till 23rd may. Kindly also suggest if it is safe to take pain killers or not. He is not corona positive now. There are no symptoms left. Looking forward for your response and kind attention. I have attached his past prescription as well. Thanks in advance.
