I gave up dairy products. What everyone else said makes a difference too, but I found that I was having a reaction to dairy products which was causing inflammation. Last year I went to a neurologist who did some tests and recommended surgery, about 6 months ago I eliminated all dairy, last month I went back to the doc for follow up, she tested me and was pleased with the results. I still get a little sore after a busy week, but the pain and weakness is gone. 2¢ WC
