Hello, I am 28 years old, 180 lbs, 5'6" and I always have a red blotchy patch on my throat, where my thyroid would be that itches sometimes. The redness comes and goes, but is there quite a bit. I'm wondering if it has something to do with my thyroid. I have been tested for thyroid disorder twice before, both times it was borderline low so they didn't do anything about it.
