the only one i know is specifically for sciatica, but that's the biggest place where i get joint problems so it might help if it's similar to mine... not sure if you might have tried it yet, but the stretch my chiro taught me is one where, sitting in a chair or on the edge of your bed, you put your foot on the side that hurts over your other knee, then lean forward. as with all stretching make sure you do it slowly and gently and stop if it makes the pain worse. you may need to do it a few times throughout the day to get it to help too.

I'm up to try anything so this sounds like I can definitely give it a go as it's at home! Thank you ❤️
