Sudden Joint Pain: Any Ideas?

Here's a weird one so I get these random moments where my joints will randomly cause me extreme pain usually my knees wrists or hips like ill be walking just fine then take a step and boom I'm on the floor cause it just decided to stop working properly and be painfully whenever I put weight on it? I don't think it's pinched nerves cause usually shaking my leg or manipulating the area it will suddenly stop hurting so if anyone might have an idea what this is I'm open for it!
