Awesome information! Thank you so much! The best thing about what you told me is that I can do those things myself and they are beneficial to anyone whether they have PN or not. As far as T3 and T4 those weren't tested. For thyroid my doctor only test TSH with reflex to T4 (that's exactly how the test states it). They have tested it twice and used the same test both times. How would I get the other things tested? I hate to walk in demanding and acting like I know more about it than they do. But sometimes we have to be that way I guess. I will read up on the information you gave me. I just want to thank you again!
