I have had intermittent lower abdominal pain for the past week, with severe worsening last night; should I seek urgent medical evaluation?

You need urgent medical evaluation, ideally within 24 hours or sooner if symptoms worsen

Given your week-long intermittent lower abdominal pain with severe worsening last night, you should seek prompt medical evaluation to rule out serious conditions that could affect your health and potentially require urgent intervention.

Why This Matters

Lower abdominal pain with acute worsening raises concern for several potentially serious conditions including:

• Diverticulitis (inflammation/infection of colon pouches)
• Appendicitis (though typically right-sided)
• Bowel obstruction or perforation
• Gynecologic emergencies (if you have female reproductive organs - ectopic pregnancy, ovarian torsion, pelvic inflammatory disease)
• Complicated urinary tract conditions

The pattern you describe—intermittent pain progressing to severe pain—is a red flag that suggests evolving pathology rather than benign, self-limited disease 1, 2.

What Your Doctor Will Look For

Critical warning signs that demand immediate emergency room evaluation:

• Fever (suggests infection/abscess)
• Persistent vomiting
• Blood pressure drop or feeling faint (systolic BP <100 mmHg has a 7-fold increased likelihood of serious illness) 3
• Inability to pass gas or stool
• Rigid, board-like abdomen
• Severe pain that prevents normal activities

Important clinical details:

• Exact pain location (left vs. right lower quadrant guides different diagnoses) 4, 5
• Associated symptoms: fever, nausea, vomiting, changes in bowel habits, urinary symptoms
• For those with female reproductive organs: pregnancy possibility, menstrual history, vaginal discharge 2

Expected Diagnostic Approach

Initial workup will likely include:

• Blood tests: complete blood count, C-reactive protein, liver/kidney function 2, 6
• Urinalysis and pregnancy test (if applicable) 2
• CT scan of abdomen/pelvis with IV contrast - this is the gold standard for lower abdominal pain when the cause is unclear, as it changes diagnosis in 51% of cases and admission decisions in 25% of cases 1. CT is far superior to plain X-rays, which have limited value 1, 6
• Ultrasound may be used first if gynecologic causes are suspected in premenopausal women 4

Common Pitfalls to Avoid

Do not delay seeking care because:

• Pain comes and goes (intermittent pain can still represent serious disease)
• You can still function somewhat (elderly patients especially may have minimal symptoms despite serious infection) 1
• You're hoping it will resolve on its own (the acute worsening suggests progression)

Clinical accuracy without imaging is insufficient - even experienced clinicians cannot reliably diagnose the specific cause of acute abdominal pain by examination alone, which is why imaging plays such a crucial role 1, 6.

Bottom Line

The combination of week-long symptoms with acute severe worsening creates a clinical scenario where serious, potentially surgical conditions must be excluded. While one-third of acute abdominal pain cases never receive a definitive diagnosis and resolve spontaneously, another third have serious pathology requiring intervention 1. You cannot safely distinguish between these categories without medical evaluation and likely imaging.

If you develop fever, vomiting, inability to eat/drink, worsening pain, or any of the warning signs above, go to an emergency room immediately rather than waiting for an appointment.
