On October 8th, I received a full thyroidectomy and removal of lymph nodes. A few month before this, two nodules were discovered on the right lobe of my thyroid. They were biopsied and one came back suspicious and with it being over 2 cms. The other "benign" nodule ended up being some form of a cyst that also needed to be removed. I went in under the impression it would only be the right lobe coming out but when the pathologist viewed the right lobe - apparently he decided a full cancer surgery needed to be done. I was released on 25 mg 2x of Cytomel. I went back in for my post op appointment where I was told I had "thyroid cancer" and although my cancer hadn't reached my lymph nodes quite yet, I would need RAI. I just recently saw my original Endocrinologist and was told that 2 weeks prior to the RAI that I would need to stop taking my Cytomel completely and go on a low iodine diet. I was also informed that I would be sick. He didn't go into the specifications of the pathology or how sick I would be. So, my question is... How sick will abruptly going off the Cytomel make me and how does the RAI typically effect you? When will I know what form of thyroid cancer I have... I mean, does it come later on that they tell me all this? I've also been experiencing a quaky shaky feeling in my legs and what feels like low blood sugar. Is this normal?
