Is your doctor running any tests, other than TSH to test thyroid function? You need, also, to have Free T3 and Free T4 tested. Diagnosis and dosing of medication, should never be done, solely on the basis of TSH.... Oops, I see that you had an FT4 of 0.91; what's the reference range for that? Reference ranges vary from lab to lab, therefore, must come from your own lab report.......
That said, if the range your lab uses is like what we see most, it will be something like 0.8-1.8, which would make your result of 0.91 very low. You also need to have your Free T3 tested, since there may be a chance that you aren't converting the T4 to T3. In addition, most of us find that FT3 correlates much better with symptoms, than either TSH or FT4.
Many of us, with Hashimoto's experience the occasional "flare" of thyroiditis; my bouts are becoming less often and less severe as time goes on. I do find that taking a daily dose of selenium helps to reduce, both, the severity and frequency. I found, too, if I placed a cool cloth over my thyroid area, it seemed to help with the pain. I also took, aleve to help ease the pain; however, your doctor has recommended motrin, so that's what you should use. Be sure not to rub or irritate the thyroid area -- this seems to really get the antibodies in an uproar!!
While getting well can be a long drawn out process, I hope you both get to feeling better soon.
I sympathize with you - after several months on Armour thyroid and feeling much improved from my former condition (intense fatigue, very dry skin, nausea, weight gain, muscle weakness, eye dryness, ear infections (weird at my age of 56) etc...I have a feeling of tightness and mild but unrelenting pain in my throat (thyroid location) I feel like something is stuck, like I cannot swallow a bite of food.
I have multiple nodules with one primary (largest) of 1.4 cm. It has been FNA biopsied twice (benign) The May 2010 blood work (my original diagnosis) returned with anti-TPO auto-antibodies confirming Hashimotos Thyroiditis.
I guess I thought I was on the down-side of the disease, that my own tissue was pretty well burnt-out from the invasion of antibodies killing it off - but now I think I am going through an attack of thyroiditis (higher level of inflammation) which is causing the swelling.
So my answer is yep, I am experiencing pain and swelling - although not a burning sensation. Also, I am feeling emotionally depressed.
