I am also curious to read... 2008 a surgeon dr. was seeing about a bowel issue for first time said; do you have a goiter? By the time I realized what that was he had his hand on my neck and said yes you do...then we went on to discuss a possible colonoscopy.
His report of my visit to my family dr did not mention the goiter. A month later I went to GP as had heard new Gastro in town and asked if I could have him do colonoscopy instead of surgeon.. and during conversation I said to him: oh the other dr said I have a goiter. My GP felt my neck.. oh I DONT feel anything he said! Well I said, why did he say I did?
Anyway GP sent me for ultrasound and yes goitre on R. thyroid and quite large.
Long story short, had the goiter and right thyroid removed. 2.5 hour operation 2 nights in hospital, and have since been on daily Synthroid.
Left thyroid has small nodules in and I go every year for ultrasound since 2009 and they are just leaving them for now as small. Should they get bigger I am to be referred to an ENT.
Having no family dr for past 2 years, I suppose I am now supposed to keep track of this problem? We have 2 ENTs where Ilive and one is a year wait it not urgent and the other 2 years! (Northern Ontario)

Best of luck and anxious to hear your results.. also, I find they do the one thyroid blood test yearly, whereas there are several blood tests they can and I feel should do - maybe ask for them all, I might. 🙂
