Neck lumps are abnormal swellings or masses that appear in the neck area. They can develop due to various reasons such as infections, enlarged lymph nodes, cysts, thyroid problems, or in rare cases tumors. Neck lumps may be painless or accompanied by symptoms like pain, difficulty swallowing, or fever. While many neck lumps are harmless and temporary, persistent or growing lumps should always be evaluated by a doctor for proper diagnosis and treatment.
