Help! My legs hurt when I stand or walk

I know it's really hard but I have found that sometimes when I really hurting I get up & move around it really does help with the pain. I had both knees replaced & if I sit too long I can barely walk when I first get up but every step gets less painful

I’m having the same problem but mine starts in my lower back. Makes me want to cut them off but my doctors say everything is normal. 🙄

Can you describe the pain? I just had a knee replacement and need another one probably next year.
