A hernia ultrasound is a targeted scan that may help assess a suspected abdominal-wall or groin hernia when the clinical question is suitable. It does not replace urgent surgical assessment if a lump is painful, cannot be pushed back, or occurs with vomiting or severe abdominal pain.
I use this page to explain the purpose and limits of a hernia ultrasound. The scan may show a defect or tissue movement in the abdominal wall or groin, often while you change position or perform a gentle manoeuvre as directed by the clinician.
A visible lump does not always cause the pain, and a scan result does not decide treatment on its own. Your symptoms, examination and surgical advice guide the next step.

What the scan may assess
Ultrasound can be useful when a clinician needs to assess a focused abdominal-wall or groin concern. Dynamic imaging may be used because some hernias are easier to demonstrate with a change in position or pressure.
| Question | What a clinician may consider |
|---|---|
| A lump appears with standing or coughing | Focused examination and dynamic ultrasound where appropriate |
| A groin pain pattern is unclear | Clinical review because pain may have several causes |
| A prior repair has new local symptoms | Surgical or GP assessment, with imaging if it answers a defined question |
| Painful irreducible lump or vomiting | Emergency assessment rather than routine imaging |
What happens on the day
The clinician asks about the lump, previous operations, pain pattern and symptoms such as bowel change or vomiting. They may scan while you lie down and while you stand. The exact technique depends on the area and the clinical question.
After the scan: report and next steps
The clinician or reporting team will explain how your report is shared and what follow-up is appropriate for your symptoms. The reporting route, timing and whether GP or surgical referral is indicated are confirmed at booking and reviewed in the clinical context. A scan result does not replace urgent surgical assessment if symptoms suggest a trapped or complicated hernia.
Urgent symptoms need a different route
Seek urgent medical help for sudden severe pain, a tender lump that will not reduce, vomiting, abdominal swelling, fever, fainting or marked deterioration. These symptoms can need urgent surgical assessment.
Call 999 or attend A&E if severe pain, vomiting or a trapped painful lump suggests an emergency. Do not wait for a routine ultrasound appointment.
