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 lasts 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 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.
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
