The thyroid gland is located at the throat, immediately under the chin, and surrounds the jugular, esophagus and trachea on either side.

There are various tests that can confirm the diagnosis of a thyroid gland disorder. Regarding blood tests, the most common is the TSH (thyroid stimulating hormone) test. However, there are several other blood tests that can help determine the overall health the function of the thyroid gland.Related Article - An Overview: Understanding Thyroid Blood Tests
These symptoms are too vague to guess a diagnosis, however a common diagnosis with this set of symptoms is goiter resulting from autoimmune thyroid disease which can be present with normal thyroid labs.
Diffuse thyroid parenchymal disease just means disease of the thyroid throughout the body of an organ. It is not a diagnosis, but only an observation based on thyroid ultrasound.
The areas supplied by the carotid artery are primarily drained by the internal jugular vein and the external jugular vein. The internal jugular vein collects blood from the brain, face, and neck, while the external jugular vein drains the superficial structures of the head and neck. Additionally, smaller veins such as the facial vein and the thyroid veins also contribute to draining regions supplied by the carotid artery.

Thyroid function tests (TFTs) are the main diagnostic criteria for a thyroid disease. These are however done in the face of other clinical findings and patients symptoms (differs for hypo and hyperthyroidism)
Primary hypothyroidism is caused by a deficiency in the thyroid itself. Secondary hypothyroidism is caused by an "outside" influence, usually a medication that causes the thyroid to not secrete the necessary hormones or an insufficient quantity, or may be caused by a primary disease process that in turn affects the thyroid gland. Sometimes secondary hypothyroidism is caused by the treatments for cancer, for example.
Secondary hypothyroidism is a condition where the thyroid gland produces insufficient hormones due to a problem with the pituitary gland, which fails to produce adequate thyroid-stimulating hormone (TSH). This can result from various factors, including tumors, trauma, or other diseases affecting the pituitary. Unlike primary hypothyroidism, where the issue originates in the thyroid itself, secondary hypothyroidism indicates that the pituitary gland's dysfunction is the root cause of low thyroid hormone levels. Diagnosis typically involves assessing TSH and thyroid hormone levels, along with imaging studies if necessary.
