Doctor's Say Nothing Wrong, but Still Not Sure...
I have been suffering from extreme fatigue for several years now. I can literally fall asleep at any time of day and still never wake up rested. I also have random other symptoms that may not even be connected, but thought I'd mention of sensitivity to cold, breathlessness, dizziness when standing, blurry vision when just standing, and acid reflux. When I was 18, I had an abnormal thyroid test that was repeated every 6 months for a year or so, but never came up abnormal again. I don't know what it was because I never thought to ask. I was tested in 2007 (TSH only) and it came back at 3.076. This was just part of some random physical test. I was tested regarding my symptoms in 2009 and the results were super different:
FT3 2.8 (ref. 2.3-4.2 pg/mL)
TPO less than 10 (0-34 IU/mL)
T4 8.4 (4.5-12.0 ug/dL)
TSH 1.2 (.45-4.5 uIU/mL) --way within normal, almost low
FT4 .99 (.61-1.76ng/dL)
B12 was a little low. I also had lower Lymphocytes and liver enzymes, but only slightly.
In June of 2012, I visited a doctor for my continuing symptoms, and my TSH was tested again, among other things. The result was 3.130 uIU/mL (ref. .45-4.5) which shows a lot of fluctuating. I know that the new suggested range for TSH is a max of 3, but still I was only slightly over, and varied over the years. Could the thyroid still be a problem? THe only time anything but TSH was tested was in 2009.
