Swollen lymph nodes in the female groin area can be caused by injury, a viral or bacterial infection, or a sexually transmitted disease, according to the National Institutes of Health. Patients with swollen groin lymph nodes should see a doctor in order to get a precise diagnosis.

Additionally, swollen lymph nodes in the groin area might be related to the legs or feet and not to the groin area at all, advises WebMD. Other possible causes include hernias, allergies, drug reactions and benign cysts. In rare cases, swollen lymph nodes signify cancer. However, sometimes lymph nodes swell for no reason at all, which is why it is best for those concerned to check with a doctor.

Lymph nodes are small glands located throughout the body and are an important part of the immune system. The nodes filter the body’s fluids and trap unhealthy bacteria and viruses so they can be destroyed, explains WebMD. This is why lymph nodes often swell when there is an infection in a nearby area. For example, the lymph nodes in the neck might swell when an individual has a cold. In addition to the neck and groin, the armpits also contain lymph nodes that can be felt by touch.
