If your thyroid is not working properly, neither are you
You need a glass of water and a handheld mirror.
Your thyroid is located - on the lower front area of your neck, above the collarbones and below the larynx. Don't confuse the Adam's apple with the thyroid gland. The thyroid gland is located further down on your neck, closer to the collarbone.
If you see any bulges or protrusions in this area, see your physician. You may have an enlarged thyroid gland or a thyroid nodule that should be checked.
