In April the last year (so it has been a year since then) I am diagnosed with viral thyroiditis (Subacute thyroiditis).According to Ultrasound, My thyroid is inflamed and enlarged. I took prednisone for several months for the inflammation and as this case caused me hypo I took thyroxine 75 for 7 months. When testing anti bodies for Hashimoto,the result was negative.For the last year,there was good days and bad days but generally I felt better at the end of the year,and the blood test for thyroid functions was good as I took the 75 dose ( My TSH was 2.1 with this dose).Then My doc told me to stop taking thyroxine as the inflammation was temporary and he wanted to know if my thyroid will work again from itself.Therefore, I stop taking thyroxine for 2.5 months. After I stop the medication, I suffered from thyroid pain,skipped heart beats, feeling hot all the times, sweating despite the cold weather.But I decided to wait to stimulate my thyroid to work again without thyroxine. Today, I got the lab results and these are the results without thyroxine for 2.5 months.
TSH 7.33 (Ref. 0.4- 5.0)
Free T4 .87 (Ref. 0.8- 1.9)
Free T3 2.1 (Ref. 2.0-4.4)
What do you think? Can the temporary condition of virus infection of the thyroid turn me hypo for ever ? Do I need to retake my medication or the thyroid can work again from itself if I wait longer as this is not an immune disease ?
Thanks for your support.
