Question about my Hyperthyroidism treatment

[JohnM81]

I am a 28 yo male who has been diagnosed with hyperthyroidism. I went to an endocrinologist and she did a sonogram she did say I had a small nodule. She said I had a slight goiter and put my on MMI. My T4 was pretty high and my TSH was very low. After about a month on the drug I was feeling like a new man. Around the second or third month something started to happen. I started to get this strange tingling sensation near my thyroid and it feels very tender. I get the sensation my neck is slightly swollen. The blood work has shown that my T4 is in normal range and my TSH not only returned to normal but swung into the hypothyroid range. So I have responded to the MMI very well. Every time I see the doctor I she lowers my MMI but it seems my tender thyroid and swollen feeling still remains. My TSH is still a on the high side but is coming down slowly. When I started out my TSH was around 0.1 and now its over 5.

My question is are these symptoms that I am experiencing normal? And if so when can I expect them to go away?


Thanks for your time,

Would keep decreasing the MMI as the TSH seems consistently high on treatment; may be able to come off the MMI.  It may not have been graves, but rather thyroiditis as the cause of the hyperthyroidism - in these cases, it is self-limited and medications are not needed.  Also, thyroiditis is more likely than graves to cause pain in the thyroid.

I never had this swelling feeling, pain, or anything else before my TSH increased. Could that indicate that the large swing in TSH could cause inflammation of the thyroid?
