I also hope that you'll get some relief. I imagine its hard to even consider seeing more doctors after all the ones you've seen that didn't diagnose you properly, but it would be a good idea to see another one. There is also an excellent video by Dr. Casey if you haven't already seen it. I'll see if I can find the link and post it here.

Here is the video link. Its about 2 hours long so watch it if you can. There is a lot of good info.
