Groin lump
A groin lump is swelling in the groin area. This is where the upper leg meets the lower abdomen.
Considerations
A groin lump may be firm or soft, tender, or not painful at all. Your health care provider should examine any groin lumps.

- Infection in the legs
- Body-wide infections, often caused by viruses
- Infections spread through sexual contact such as genital herpes, chlamydia, or gonorrhea

When to Contact a Medical Professional
Small lymph nodes that can be felt in the groin are common, especially in men, and usually result from prior leg infection. Make an appointment to see your provider if you have an unexplained groin lump.
What to Expect at Your Office Visit
The provider will examine you and may feel the lymph nodes in your groin area. A genital or pelvic exam may be done.
You will be asked about your medical history and symptoms, such as when you first noticed the lump, whether it came on suddenly or slowly, or whether it gets larger when you cough or strain. You may also be asked about your sexual activities.
