Neck swelling refers to an abnormal enlargement of the tissues in the neck area. This condition can result from various causes, including infections, inflammation, or the presence of tumors. Common reasons for neck swelling include lymphadenopathy, where lymph nodes become enlarged due to infection or illness, and thyroid disorders, which can lead to a noticeable swelling in the front of the neck. In some cases, neck swelling may be accompanied by other symptoms such as pain, difficulty swallowing, or fever. It is important to seek medical attention if neck swelling persists or is associated with severe symptoms, as it may indicate a more serious underlying condition.
