When to Contact a Medical Professional
Make an appointment to see your health care provider if you have an unexplained groin lump, especially if it persists for more than 3 weeks.
What to Expect at Your Office Visit
The health care provider will examine you and may feel the lymph nodes in your groin area. A genital or pelvic examination may be done.
You will be asked 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 health care provider 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 infections
- Kidney function tests
- Liver function tests
- Liver spleen scan
- Lymph node biopsy
