What to do if…
you develop steadily worsening pain in the lower right side of your abdomen

Short answer

Treat steadily worsening lower-right abdominal pain as urgent. If it’s severe or suddenly worse, you faint/collapse, you’re very unwell, you can’t pee/poo, there’s blood in vomit/poo, or you might be pregnant, go to A&E now or call 999.

Do not do these things

  • Do not “wait it out” overnight if the pain is getting worse hour by hour.
  • Do not eat a large meal “to keep your strength up” while you’re arranging urgent assessment.
  • Do not take laxatives, use enemas, or try to “force a bowel movement.”
  • Do not use heat in a way that could mask how quickly the pain is worsening (and do not let it delay you getting assessed).
  • Do not drive yourself to A&E if you feel faint, drowsy, very unwell, or the pain is severe.
  • Do not take leftover antibiotics or start a new medicine to “see if it fixes it.” If you take pain relief, keep it minimal and note what you took and when.

What to do now

  1. Decide your urgent care route (now).
    • Call 999 or go to A&E immediately if: the pain is severe, suddenly gets much worse, spreads, you faint/collapse or feel very dizzy, you’re confused, you’re struggling to breathe, you’re vomiting blood, your poo is bloody/black, or you cannot pee/poo.
    • If it’s steadily worsening (even if you can still function), call NHS 111 for urgent advice and likely same-day assessment. (In Scotland, NHS 24 is reached via 111.) If you can get through quickly, you can also contact your GP / out-of-hours service.
  2. If pregnancy is possible (even uncertain): treat this as urgent today. Go to A&E now (or call 999 if you’re very unwell) if one-sided pain is accompanied by vaginal bleeding, shoulder-tip pain, weakness, dizziness, or fainting.
  3. Avoid large meals; take small sips of water if you need to. Don’t drink alcohol. If you have diabetes or need regular medication with food, follow your usual safety needs and tell 111/A&E what you’ve taken.
  4. Write down a 60-second timeline to take with you. When it started, where it began, whether it moved, how fast it’s worsening, vomiting/diarrhoea/constipation, fever/shivers, urinary symptoms, vaginal bleeding/discharge, last period/pregnancy possibility, and any recent injuries.
  5. Arrange safe transport and support. Ask someone to come with you if possible. If you live alone, message/call someone now and tell them where you’re going and that you’ll update them after you’re assessed.
  6. Pack the essentials (2 minutes). Phone/charger, any key medical info (medications/allergies list or photos), and a small overnight item if you can do so without delaying leaving.

What can wait

  • You do not need to work out the cause (appendix, ovary, kidney stone, bowel, etc.) before seeking help.
  • You do not need to “prove” it’s an emergency or finish chores beyond a brief message to cancel plans.
  • You do not need to decide about scans, surgery, or treatment options until you’ve been assessed.

Important reassurance

Lower-right abdominal pain that steadily worsens is a common reason people need same-day assessment, and getting checked promptly is the safer choice. Many causes are treatable—what matters is not missing the ones that become dangerous if delayed.

Scope note

This is first-step guidance for the next few hours. The clinicians who assess you will decide what tests or treatment you need based on your exam and results.
