Hey Eerbes,
I can relate to your post-- it's pretty much what one of my many questions were going to be on this health board. :/
I've gotten back nothing but a bunch of "normals," all my life and have felt everything but. Do you seem to get new issues each year whether they stay or not? And is there a specific moment where you noticed you started getting sick all the time?
I've recently gotten my blood drawn (again!) and am assuming that my results are not going to show anything is going on; as usual. (This is even the second time I've gone to an Endocrinologist and now I've come full circle because I've been redirected to my primary doctor)

I'm sorry you're going through this, too. I wish this reply was a helpful answer.
