Anti inflammatory diet is a huge focus for me with chronic pain from scoliosis. If you google anti inflammatory diets you'll get some good lists of food to include in your diet as well as ones to exclude. Thankfully by sticking to primal most inflammatory foods will be gone anyway.
I drink lots of green tea, minimum of two cups a day. Try to include things like flaxseed, turmeric, berries (blueberries are best), kelp and keep your intake of dairy very low.
