If you rub Lucy’s neck, you’ll feel some pea-sized lumps within the muscle. These so-called lymph glands or lymph nodes are a normal part of our immune system, designed to kill germs and then process them. Whenever there’s a germ attack in the area, the lymph glands close to the site swell up and become much more noticeable for a few months. As long as these lumps are small and painless and move under your finger, you can ignore them, although they will be there for a few months. In rare cases, these lymph nodes can become red, enlarged, and tender when infected by the very germs they’re supposed to destroy. Your doctor will treat the condition with an oral antibiotic.
