Hi! I am a 20 yr old female diagnosed with hypothyroidism on January 2011. I went to the doctor for a routine test, and because my mother has hypothyroidism, my doc annually checks my TSH levels. I went to the lab to have my blood test that particular day because I felt good and haven't been sick in some time. To my surprise, when I received my results, everything was normal except my TSH, it was 20.20 but my T3, T4 and T7 were normal.
T3-U - 33.98 % Range: 22.0 - 40.0
T4 Total - 6.70 ug/dL Range: 4.50 - 12.0
T-7 - 2.28 Range: 1.20-4.70
I was in shock, I felt completely normal, no symptoms, nothing. My doc prescribed me Synthroid 0.025mg and told me to get my TSH tested again after 6 weeks of treatment. I started taking the pill and I didn't felt any change at all, not better, not worse. At the 4th week of treatment I started feeling different, I had two episodes of high blood pressure (chills, felt like i was going to faint) and started to feel a lump in the front-right side of my neck and it causes pain and discomfort whenever i apply pressure on that side when I bent down, make some force, tilt my head, talk loudly or laugh.
After 6 weeks I got tested again and everything was fine, my TSH was 1.74 and my T3, T4 and T7 were normal again.
T4 Total - 9.60 ug/dL Range: 4.50 - 10.90
TSH 3rd Generation - 1.74uIU/ML Range: 0.51 - 6.27
FTI - 2.81 Range: 1.01 - 4.03
Then, the doc gave sent me to do a sonogram. The results say: Thyroid gland diffusely heterogeneous and nodular in echotexture bilaterally in a symmetric fashion. Isthmus measures 0.4cm. Right lobe measures 1.8 x 2.8 x 4.3cm and left lobe 1.9 x 2.2 x 4.4cm. No suspicious solid nodules on either side. A tiny cystic lesion is seen in the left gland laterally, at the mid pole in measuring 0.3 x 0.4 x 0.5cm. No abnormal lymphadenopathy. Small sublingual nodule is identified measuring 0.7cm and small submandibular lymph node is seen measuring 0.7cm and a level III nodule is seen measuring 1.2cm.
The thing is, I am having concentration problems and have failed all my college tests this semester, I can hardly say I feel good, every day I wake up feeling groggy and am always tired and restless. In addition to the two episodes of high blood pressure, I had a particular situation that thought it was pretty weird, I was taking off my hoodie jacket and it got stuck on my head so i had to pull harder to get it off and immediately after that I started feeling very sick, the front-right side of my neck started to hurt and i felt i had a golf ball in there! (but no choking sensation) I got dizzy and started to almost hyperventilate.
My doc referred me to a head and neck surgeon because she wants a biopsy of the thyroid tissue because my thyroid is very similar to my mother's and for the symptoms I have. Should I get the biopsy or it is not necessary at this moment? What do you think about my results?
