What to do when you suspect appendicitis rather than booking your own scan

Worsening, persistent abdominal pain or pain moving to the lower right needs urgent assessment. Do not spend time finding a cheap private ultrasound appointment: appendicitis needs hospital assessment, and other dangerous conditions can cause similar pain.

Use an urgent route

NHS advice is an urgent GP appointment or NHS 111 for increasing or persistent pain, including migration to the lower right. Severe pain, confusion, breathing difficulty or serious illness need A&E or 999. Do not drive yourself. NHS: appendicitis ↗.

Children, pregnant people and older adults may have atypical symptoms. Absence of the classic pain location does not justify waiting.

Explain the history rather than asserting a diagnosis

Describe onset and progression, vomiting, fever, urinary or bowel changes. Mention medicines, operations and possible pregnancy. Bring existing results, but do not delay help while collecting every document.

Possible pregnancy matters because ectopic pregnancy and other conditions need different urgent pathways. Internet self-tests cannot reliably establish the diagnosis.

Let the hospital team select investigations

Assessment can involve examination, blood and urine tests, pregnancy testing, ultrasound or CT. Not everyone needs the same scan. NHS guidance states that no test always identifies appendicitis; hospital observation of evolving symptoms is sometimes necessary. NHS: diagnosis ↗.

The team decides on surgery or other treatment using the overall evidence. Do not make one particular image a condition of further care or start antibiotics yourself.

Establish return precautions

If discharged, ask about the working explanation, review timing and changes requiring immediate return. Keep discharge instructions and service details.

Seek reassessment for deterioration despite an initially reassuring examination or scan. Brief improvement does not always mean recovery. Severe pain or serious illness require emergency care rather than waiting for booking staff. After surgery, follow your wound and activity plan; fever, pus or increasing pain require contact with the treating team.
