Hi,I have suffered with gout for many years and i don't think it's anything to do with pc treatment as it was in the family long before i had pc.You need to look up purine levels in food and drinks and also yeast and avoid beer shell fish and oily fish like mackerel etc.If you google purine levels and food and drinks to avoid this can help,I had regular attacks 10 years ago and by adjusting what i eat and drink the attacks have reduced to once every two years with help of Naproxen from my doctor when it flairs up even vegetables like Broccoli has high purines if i remember.And i also had to give up Marmite and prawns that i love.
Regards John.
