As a follow-up to my last post, I'd like to say that if you have vulvodynia, or, for that matter, fibromyalgia or other chronic pain, try changing your diet. Try it for a week. I kid you not, I saw results two days after cutting out wheat.
Where to start? Maybe I'm biased, but I'd say start with gluten. Everything I've learned about food over the past sixteen months has indicated gluten as one of the biggest villains. Gluten is a protein found in grains, but the gluten that people mean when they say "gluten-free" is from wheat, barley, and rye (and, by way of cross-contamination with wheat, most oats). Check out glutenfreeforum.com for stories about gluten and pain -- including vulvodynia.
I'm not saying a diet change will relieve everyone's pain, and it certainly didn't (or hasn't yet -- optimism!) cure mine, but it's worth a shot. It's a few days of eating carefully, and if you don't see improvement in whatever amount of time you're able to keep it up, you can go right back to those Cheez-Its (mmm...have some for me?).
Hey, I loved Donuts to the end of the Earth before going gluten-free, and now I don't even care that they exist. That's how much better I feel: Endless Donuts Better.
