I have Wilson's Thyroid Syndrome and you may very well too.
My bloodwork came out "normal" according to the MDs guidelines but my naturopath, who is familiar with Wilson's, realized it wasn't. Most docs aren't familiar with this disease. What is finally being recognized is that that (1) usually they are looking at T4 or TSH only, NOT T3, (2) That the "normal' guideliness are actually off, (3) that is also the balance
between the different levels that are important, and (4) that you can flush the system, reset it and often wean yourself off of medication.www.wilsonsthyroidsyndrome.com
will give you all sorts of information.
There were two practicing physicians in my area and I found them on the website.
I did not go on the regimen of flushing the system as I was pregnant and nursing so I take a maintenance dose of nature-throid and had great results. Our goal is to wean me off and see if even this very low maintenance dose flushes the system.
Get on the website and do your temps (10 minutes underarm, still in bed, immediately after waking - one of those nasty mercury thermometers is most accurate if you still have one around) for at least 10 days.) Ask exactly which levels were done, the exact result and what they say is the range for normal.
Both docs told me that they have used the Wilson's protocol with some people who have "normal" levels even according to their guidelines and they improved and were able to get results and wean off the meds.
I think it is obvious that we don't know all we should about the thyroid.
