I have a friend who has suffered with arthritis for a number of years. The joints of her fingers have twisted.
The pain was very bad and she was on very strong pain killers, with side affects.
The she read a article in a magazine which suggested by removing some foods from the diet the condition improves.
On the next two pages there are two lists, the foods which are okay and not okay. She gave the plan 6 months. The new diet worked for her. She no longer takes any pain relief and later this year she is to have operations to straighten her hands.
It might work for you.
