A groin lump is localized swelling in the groin area. It may be firm or soft, tender or not painful at all.

All groin lumps should be examined by your health care provider.

• Allergic reaction
• Cancer
• Drug reaction
• Enlarged lymph glands in the groin area
• Hernia (usually a soft, large bulge in the groin on one or both sides)
• Infection
• Injury trauma to the groin area
• Sexually transmitted disease

Follow the therapy prescribed by your health care provider.

Make an appointment to see your doctor if you have an unexplained groin lump, especially if it persists for more than 3 weeks.

The doctor will examine you and may feel the lymph nodes in your groin area. A genital or pelvic examination may be done.

The doctor will ask questions about your medical history and symptoms, such as:

• When did the lump develop?
• Is it on one side or both?
• How big is it?
• Did it occur suddenly or develop slowly?
• Is it always present or does it come and go?
• Does it get larger when coughing or straining?
• Has there been any unusual physical activity recently?
• What symptoms do you have?

The doctor may also ask you detailed questions about your sexual activities.

Tests that may be done include:

• Blood tests such as a CBC or blood differential
• Blood tests to check for syphilis, HIV, or other sexually transmitted diseases
• Kidney function tests
• Liver function tests
• Liver spleen scan
• Lymph node biopsy
