The glands (lymph nodes) on either side of the
neck, under the jaw, or behind the ears commonly swell when you have a cold or
sore throat. These glands can also swell following an injury, such as a cut or
bite, near the gland or when a tumor or infection occurs in the mouth, head, or
Swollen glands caused by an injury or minor infection usually go away
within a couple of weeks after you recover from the injury or illness. Young
children may have small, hard glands for weeks before the glands return to
normal. Glands that swell because of a more serious illness or tumor require
treatment for the underlying cause.
Lumps in the neck or throat also may be caused by:
A growth on the thyroid gland (thyroid nodule). An enlarged thyroid gland also may be
caused by a
thyroiditis. Most thyroid nodules are harmless,
although a small number may be cancerous.
