I'm a 20 year old male with metastatic papillary thyroid cancer! I've had a TT, neck dissection, and one round of RAI (300 mCi). My RAI was back in August, and I'm experiencing some extremely unpleasant side effects. My salivary glands are constantly swollen and painful, and my mouth is extremely dry. I know this is relatively common with RAI, I'm just wondering if anyone else has experienced it and, if so, did it clear up eventually? Thanks so much!!
