I'm 14 years old. A month ago, I discovered that I have a toxic swelling of my thyroid gland (goiter). It became visible last year July but I wasn't alarmed because the first time I noticed the swelling, was when I had a sore throat. I found out that goiter usually only occurs in adults. I did numerous tests and i'm currently on medication. Could a complication develop because of my age? Could I actually die from this? If I did surgery, is it possible that it could reoccur?
