Patients with bumps on top of their necks that are touchable and not painful are clinically common for the following reasons: a. Lipomas in the neck. Diffuse thickening of subcutaneous adipose tissue in the patient’s neck can form lipomas locally, manifesting as multiple bumps at the neck. Since lipomas do not have obvious pain symptoms, patients with smaller lesions are advised to observe them closely and do not need to undergo surgical removal. For larger lipomas that cause local distension and discomfort or affect the patient’s aesthetics, surgery may be considered to remove the lipoma. When the size of thyroid adenoma increases significantly, it may bulge outward and be felt as a lump in the neck. Adenomas often do not have obvious painful symptoms. Patients can have ultrasound examination of the thyroid gland to clarify the size and nature of the thyroid lesion. For larger thyroid adenomas, surgery is recommended to avoid local compression of nerves, trachea and blood vessels.
