I haven't been diagnosed with a thyroid condition but I did have an ultrasound and they discovered that my thyroid was full of cysts.  The rheumy was the one who picked it up and many people comment on my swollen throat.  When my flare ups are bad I do feel as though my thyroid is more swollen.  I have also noticed a corelation to diet.  If I eat a lot of white flour/yeast I seem to have issues with swallowing. I then have to eliminate it from my diet for a few days to a week and it then seems to go back to normal.

Hope this assists.

The dr's keep re-testing my thyroid and it does feel a bit enlarged and sometimes have difficulty swallowing. Not sure if that part is related to the neurological problems I've been having lately.  All the thyroid tests come back fine though.

I have a goiter on my Thyroid and I take daily Thyroid medicine.

I have Hashimoto's Thyroiditis and therefore symptoms of my IBS were not picked-up, Dr's had assumed that the changes in my bowel habits were reflective of my fluctuating Thyroid levels.
I have now made the connection that consuming starch derived from Corn as well as significant levels of stress causes me to AS flare-ups which are characterised by severe back pain, headaches (migraines), feeling like I have swollen all over, funny taste in my mouth, burning urine and poor circulation.
I am managing the flare-ups by getting the corn out of my system, reducing my stress and doing gentle exercise. I have been doing some walking meditation which has been especially beneficial as I need to rest/relax but also stay active.
