Swollen Glands and Other Lumps Under the Skin - Topic Overview
Most swollen glands or lumps under the skin
are not cause for concern. 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.
More serious infections may cause
the glands to enlarge and become very firm and tender. Glands can also swell
and become tender after an injury, such as a cut or bite, or when a tumor or
infection occurs in the mouth, head, or neck.
