Thanks for mentioning the upcoming 7-Part Autoimmune Docuseries @Indy51. I just learned about it last night.
Starts early Tuesday morning in the US. Don't know what time or day that translates to in other parts of the world - (click on the link in Indy51's post above or my signature line below to watch a video about the docuseries)...
It certainly could. My thyroid is swollen like a donut around my neck. Apparently it had been deemed non urgent and I will have to wait months for an ultrasound.
