I have had thyroid issues most of my life. Believe symptoms showed in college at 22 when a throat specialist examined my neck and mentioned enlargement but never referred me to an endocrinologist . So, I had my tonsils removed. It was not until my 50's thatI was diagnosed. Even then they could not tell me how I got this. It wasn't until I found an endocrinologist and wa told it was Hashimoto disease which runs in the maternal side of my family. I have been on Synthroid since. Would like to know what this LDN is.
