Oh thats brilliant, its very rare in England to find both a medically and holistically trained doctor all in one! Dr Myhill who wrote THE book on Chronic-Fatigue-Syndrome is, but the waiting list is years long to see her unfortunately.
I think its very useful to find a doctor of that nature when going the natural route, so many 'ND's' are not qualified and dish out supplements and potions with no true understanding what they do or how they work, and a lot of people get damaged by them.
YEs an endo probably would look towards synthetic hormone replacement depending on your results...however I know a LOT of people who had 'thyroid' issues, were treated by synthethic hormones and then a year later are off meds and totally fine. Western medicine is trained to deal with problems when they see them through there hugley wide markers! but ive just noticed you mention on the message below your counts are in range...if so, then an endo probably wouldnt help but sounds like youve got a good fellow in this MD ND!
