I've recently got a really bad attack of gout. Which baffles me because I've had it for a couple years now and have finally changed my eating habits and lifestyle to be healthier. Yet, here I am still suffering from it.

-I take allopurinol daily. I take indomethacin and ibuprofen during flare ups.
-I am on a low carb diet. I've lost 30 pounds.
-I do not eat sugary foods or drink sugary drinks.
-I seldom drink alcohol (maybe once every few weeks I'll have some liquor during social gatherings.
-I do not eat organ meats and seldom eat red meats (maybe once a week I'll have some hamburger or a steak.) Mostly I focus on lean chicken.
-I drink LOTS of water. 2-3 liters a day.
-I exercise often, walking 2-3 miles a day.

I don't get why I'm still suffering from it. What else can I do to fight against it? I thought avoiding the sugars and bad stuff, turning my diet and exercise levels around would help me. Its discouraging and really irritating to be in pain all the time. I currently have the gout in my knee and my ankle.
