Acute thyroiditis generally refers to acute suppurative thyroiditis, a type of pyogenic infectious disease. For instance, many patients may exhibit symptoms of an upper respiratory tract infection or experience swelling, pain, or difficulty swallowing in the lateral aspect of the thyroid in the anterior neck following a fine needle aspiration biopsy of a thyroid nodule. The local skin over the thyroid may display erythema or heat, and some may also have systemic symptoms of a febrile disease, such as increased body temperature, generalized body aches, and fatigue, along with swelling and pain in the cervical lymph nodes. Thus, the primary symptoms of acute thyroiditis are infectious, accompanied by symptoms of compression pain due to thyroid enlargement.

Does thyroiditis hurt?

The most common causes of thyroiditis refer to subacute thyroiditis and autoimmune thyroiditis. Subacute thyroiditis is mainly caused by viral infection, leading to the destruction of thyroid follicular cells. This generally results in pain in the thyroid region, which can even radiate to areas like the back of the neck and ears, with the pain symptoms being relatively significant. Meanwhile, Hashimoto's thyroiditis typically does not present with pain, although a small number of patients may experience localized pain during the onset of the disease, but the symptoms are usually mild. Additionally, the pain in the neck thyroid region associated with subacute thyroiditis varies from person to person, with varying degrees of pain intensity. It is primarily treatable with steroids or non-steroidal anti-inflammatory drugs, and generally, the symptoms can be relieved after treatment.

How to check for thyroiditis?

Thyroiditis is a general term. Clinically, the most common type is subacute thyroiditis, and another is Hashimoto's thyroiditis, which are two different diseases. For subacute thyroiditis, the symptoms include fever, neck pain, and throat discomfort. Generally, the first step is to check thyroid function to see if there is hyperthyroidism or hypothyroidism. The second step is to suggest antibody tests, including anti-thyroid peroxidase antibodies and anti-thyroglobulin antibodies. The third suggestion is to conduct a routine blood test and erythrocyte sedimentation rate. Fourth, a thyroid ultrasound is recommended. If necessary, a thyroid fine-needle aspiration may be performed for a definitive diagnosis. If it's Hashimoto's thyroiditis, which is an autoimmune disease, a specific antibody, TPOAB or anti-thyroid peroxidase antibody, is used for diagnosis.

Symptoms of hypothyroidism in thyroiditis

There are many types of thyroiditis, and the most common one associated with hypothyroidism is Hashimoto's thyroiditis. Symptoms of hypothyroidism include multi-system involvement. In the nervous system, it manifests as reduced memory and attention, and drowsiness; in the cardiovascular system, it presents as bradycardia, faint heart sounds, and cardiac enlargement; in the musculoskeletal system, it manifests as slowed movement and joint disorders; in the digestive system, it presents as loss of appetite, bloating, and constipation; in the respiratory system, it manifests as weak and shallow breathing; in the hematologic system, it can manifest as anemia; in the endocrine system, it can present as reduced gonadal function accompanied by hyperprolactinemia, menorrhagia, amenorrhea or infertility, hair loss, and the skin and mucous membranes appear pale with myxedema.

How is thyroiditis diagnosed?

Thyroiditis, clinically more commonly seen as subacute thyroiditis, is primarily caused by viral infections. The main clinical symptoms include pain in the anterior neck accompanied by fever, typically in the afternoon or evening. Upon examination, the thyroid is enlarged and tender. In terms of auxiliary examinations, blood tests reveal that some patients may have elevated white blood cells if there is a concurrent infection, and an increased erythrocyte sedimentation rate. Furthermore, initially, there might be mild signs of hyperthyroidism. Thyroid ultrasound may suggest signs of subacute thyroiditis, and the iodine uptake rate is decreased. If further examination is desired, a fine needle aspiration of the thyroid can be performed to help comprehensively consider and confirm the diagnosis.
