Eating junk food, sugar, meats that have high quantity of fats and many other processed foods are considered to be a source of energy for inflammation. The reduction in the consumption of highly saturated fats and trans-fat by eating less of processed foods such as sausages, bacon and highly processed red meat is recommended. Also avoid using white flour in pasta and bread and use whole grain made products instead. Taking a small quantity of sugar is fine however; avoid using sugary sodas, rich desserts, candies, cereals that are pre-sweetened and pastries.
I have injections in my Knee every three months and they give me a pain free life with no pain killers. It varies each time but I know how effective it will be as they inject, the more it hurts the better it will be and the doctor says he can feel the needle going in to inflamed tissue and I say don't I know it but carry on you have hit the right spot. It is sore for a day or two but after that it is a win, win situation with it lasting up to 2 months and then the pain starts coming back so I have to resort to pain killers untill I am allowed another jab, only allowed 3 a year. Injection work's best on the Knee and vary's on other joints but they are well worth a try. They reach there most effective within a week and if they do not work for you then worth trying again as it is important to get it in just the right spot and the ankle is a much smaller joint.
