As the others posted, just because the blood work is good, doesn't mean every thing is fine. I am in a similar situation. All my blood work looks good, but I just don't feel as good as I did a year ago, at my last check up. I don't want things to slide out of control. As I am sure you don't. Don't give up, keep pushing for answers. You know something doesn't feel right, so make the doctor listen to you.
