Beleive me, I know exactly how you feel. I started having them 2.5 years ago and was just diagnosed a couple of weeks ago. For the first year I went through many many tests and lost a lot of money because of it. It gets really frustrating when you go to the doctor and basically hand them your life savings and then they say that i am fine. cuz all the tests came back normal. Hopefully you wont have to go through this and the test will show something.
But the good thing is tthat there are many good people on this board to talk to and they will let you just get some of these frustrations out on the board. Thank you all. And good luck to you.
