Slow Appendicitis Symptoms: What to Watch For

Appendicitis can present subacutely ("grumbling" or "smoldering" appendicitis) when the appendix intermittently obstructs and decompresses, or perforates slowly with walled-off abscess.

Typical Progression (Classic Acute)

1. Periumbilical/epigastric visceral pain (T10) – 4–6h.
2. Anorexia, nausea ± vomiting.
3. Migration to RLQ (McBurney's point) – somatic pain (parietal peritoneum irritation).
4. Low-grade fever (99–101°F), leukocytosis.

Subacute / Atypical Presentations

• Intermittent RLQ pain over days/weeks (obstruction → decompression).
• Vague, low-grade discomfort rather than severe pain.
• Minimal fever, normal WBC (especially if walled-off).
• GI symptoms dominant: Bloating, constipation/diarrhea, early satiety.
• Retrocecal/retroileal appendix: Flank/back pain, urinary symptoms, psoas sign (pain on hip extension).
• Pelvic appendix: Suprapubic pain, urinary frequency, diarrhea, rectal tenderness.

Diagnostic Clues

• History of recurrent similar episodes.
• Localized RLQ tenderness ± guarding (may be subtle).
• Rovsing's sign (LLQ pressure → RLQ pain), psoas sign, obturator sign.
• Imaging: US (non-radiation, operator-dependent), CT abdomen/pelvis with contrast (gold standard, >95% sens/spec), MRI (pregnancy).

Management

• Acute uncomplicated: Laparoscopic appendectomy (standard). Antibiotics-first strategy (non-operative) an option for select uncomplicated cases (CODA trial) – but recurrence ~30% at 1y.
• Perforated with abscess: IV antibiotics + percutaneous drainage → interval appendectomy 6–12 weeks later.
• Subacute/recurrent: Interval appendectomy after symptom resolution.

Do not ignore recurrent RLQ pain. Delayed diagnosis increases perforation risk (15–30% at 36h, higher later).
