Hey guys. I just had my first treatment of RAI this week. I was given the injections so I didn't have to come off of my synthroid.
I am 32 years old. I was diagnosed with both hashimotos and papillary thyroid cancer this summer. I had a TT. Path came back that nodual was small (8mm). I had an ultrasound done prior to surgery to check the lymph nodes in my neck and they were ok. But the central lymph nodes that came out with the thyroid were positive for cancer (6 out of 15 were positive). Because of this my endo recommended RAI treatment. After my first set of bloodwork (about a month after surgery) my t4 free levels were high so they lowered my dosage. My tg was was at <0.2. From what i understand this number doesn't matter because I have antibodies. My tg ab were at 65.
A week before I started my RAI I was tested again and my t4 was still high so they lowered my dosage again. My tg was still at <0.2 and my tgab dropped to 30. My TSH was also as <0.2
I started my low iodine diet. Had my injections. A tracer dose and WBS pre RAI. The WBS before treatment showed a little bit of uptake in the thyroid bed. I was treated with 125mci of 131. 5 days later i had another WBS and chest an next CT without contrast. I am waitin for those results and I'm really nervous because about 2 days after my treatment dose I started to get chest pains when eating and sometimes if I took too deep a breath. Alon with what feels like heartburn. And burping. Could this have spread to my lungs? Would my antibodies have dropped so much in just 2 months if there was a spread? Has anyone else had this with RAI? Without going hypo.
