Havent heard of those here in the Nordics (edit: cortisol being destructive it is not a good long term solution, hence avoided). Naproxen worked for me, but took days.

It took me two years to realize what is the source of gout. D/RNA molecules. They are 50% purines which humans dont metabolize, just excrete (other animals can metab them). None of the "what to eat with gout guides" stated this clearly, which stymies me. Anyhow, now i know to avoid eating DNA rich stuff - go milk!
