I was having some severe problems with that. First I found the major cause - eating too much chicken. Many died - but in the end the chickens won.

I still had occasional problems until I found an effective treatment. The traditional cherry juice either doesn't work at all or just works a little, but celery will knock it flat. Celery seed extract is most convenient - but the first time I tried it I had none so ate 10 heads of celery (with leaves). Relief was already quite noticeable after the first two.

Now, if I notice any joint problem, I take a few capsules and it goes away.
