Neck pain is thyroid

The neck is a very important organ in the body and is known as the second brain. There are many diseases related to the neck. Neck tingling may be caused by thyroiditis, which is a very complicated disease. Depending on the cause, the clinical symptoms and prognosis vary greatly. Relying solely on the symptom of tingling is not enough to make a diagnosis, and it needs to be judged in combination with other diseases.

Thyroiditis is a heterogeneous group of diseases involving the thyroid gland caused by various reasons. The causes are different, and the clinical manifestations and prognosis vary greatly. The thyroid function may be normal, hyperthyroid, or hypothyroid. Sometimes all three functional abnormalities may occur during the course of the disease. Some patients eventually develop permanent hypothyroidism. According to the course of the disease, it is divided into acute (suppurative), subacute (non-suppurative) and chronic. According to the cause, it is divided into infectious, autoimmune, radiation thyroiditis, etc. Among them, autoimmune thyroiditis is the most common, which can be divided into Hashimoto's thyroiditis (i.e. chronic lymphocytic thyroiditis), atrophic thyroiditis, painless thyroiditis and postpartum thyroiditis. The following mainly discusses several common types of thyroiditis.

Clinical manifestations

1. Hashimoto’s thyroiditis

That is, chronic lymphocytic thyroiditis. The peak age of onset is 30 to 50 years old, and the incidence rate in women is 15 to 20 times that in men. The onset is slow, and when the disease occurs, there is often an enlarged thyroid gland with a hard and tough texture, a nodular surface, and clear boundaries. There is often pharyngeal discomfort or mild difficulty in swallowing, and some patients may have compression symptoms. There is often no special feeling in the early stage, and the thyroid function may be normal. A small number of patients may have transient hyperthyroidism symptoms in the early stage, and in most cases, hypothyroidism has already occurred when it is discovered. Patients often experience symptoms such as fear of cold, edema, fatigue, dry skin, abdominal distension, constipation, irregular menstruation, and decreased libido. A small number of patients may develop thyroid-related eye disease. Some patients may present with coexistence of Hashimoto's thyroiditis and Graves' disease, clinically manifested by alternating symptoms of hyperthyroidism and hypothyroidism.

2. Subacute thyroiditis

This disease is self-limiting and is the most common thyroid painful disease, which is more common in middle-aged women aged 30 to 50 years old. The typical manifestation is severe pain in the thyroid gland. Usually the pain starts on one side of the thyroid gland and quickly radiates to other parts of the gland, the ear base, and the jaw. It is often accompanied by general discomfort, fatigue, muscle pain, and fever. The pain reaches a peak within 3 to 4 days after the onset of the disease and subsides within 1 week. There are also many patients who have a slow onset, which lasts more than 1 to 2 weeks. The condition fluctuates for 3 to 6 weeks. After improvement, there may be multiple relapses within a few months. The thyroid gland may increase in size by 2 to 3 times or even larger than normal, and there is obvious tenderness when touched. Within one week after the onset of the disease, about half of the patients will have symptoms of hyperthyroidism, such as excitement, heat intolerance, palpitations, tremors and sweating. These symptoms are caused by excessive release of thyroid hormones from the thyroid gland during acute inflammation. During the course of the disease, a small number of patients may experience symptoms of hypothyroidism such as swelling, constipation, chills, and drowsiness, but these symptoms do not last long and the thyroid function eventually returns to normal.

3. Painless thyroiditis

The disease can occur at any age, but is more common in women aged 30 to 50. Typically, changes in thyroid function are divided into three stages: thyrotoxicosis, hypothyroidism, and recovery. The symptoms of the thyrotoxic stage include sudden onset of nervousness, heat intolerance, tachycardia, and weight loss. In some cases, thyrotoxicosis is not obvious at the beginning, and hypothyroidism is the clinical manifestation. The hypothyroidism period lasts for 2 to 9 months and then gradually returns to normal. Some patients have persistent hypothyroidism, and 10% to 15% of patients may relapse after 10 years. About half of the patients have mild diffuse enlargement of the thyroid gland, which is hard in texture, without nodules, pain or tenderness.

4. Postpartum thyroiditis

Occurring within one year after delivery, the patient's thyroid gland may be slightly to moderately enlarged, with a medium texture and no tenderness. The typical clinical course is biphasic hyperthyroidism and hypothyroidism. The hyperthyroidism stage occurs within six months after delivery and lasts for 1 to 2 months, with symptoms such as palpitations, emotional agitation, heat intolerance, fatigue, etc. The hypothyroidism stage occurs 3 to 8 months after delivery and lasts 4 to 6 months, with symptoms such as fatigue, inattention, constipation, muscle and joint pain and stiffness. The recovery period occurs 6 to 12 months after delivery, and about 20% of patients may have persistent hypothyroidism.
