I was putting some lotion on my face and neck as I have drier skin that I used to and I noticed that when I tilt my head back and place my hand on the front of my neck and gently run down with my thumb on one side and my other fingers on the other side that there is a difference. On one side the thumb goes down vertically without a problem, but on the other side I can't go down straight I sort of have to go around "something" before I go down straight again.
Are the two sides of a thyroid meant to be the same size or is it like feet for example where one might be slightly bigger?
