I suspect you came here because you've been having symptoms yet the doctors keep telling you everything is "normal".
Just because thyroid lab results are in the normal range does not mean they are YOUR normal.
Endo Dr. Ken Blanchard discusses this in his book "What Your Doctor May Not Tell You About Hypothyroidism".
Now, I don't know what might have transpired during your conversations with the various doctors that have checked your thyroid. I do think it's a good idea to bring a comprehensive symptoms list to share with any doctor.
Here's a pretty good list of things you might want to discuss with a potential thyroid doctor (see post #4):
Dr. Blanchard's book also has a section on how to talk to your doctor or any doctor from whom you seek thyroid care.
Please don't be surprised if you get nowhere with the endo.....they are usually the worst at diagnosing and treating thyroid disease.
You might want to try a DO, internist or holistic doctor - they tend to be more thyroid-savvy.
Another idea would be to call local pharmacists and get contact info for doctors that Rx Armour and/or Cytomel - these are both T3-containing meds that thyroid-savvy doctors Rx.
Many of us had to see a succession of doctors before finding one that could properly diagnose and treat thyroid disease.....I'm on #5 myself.
Best of luck to you - please keep us posted
