Appendicitis Symptoms, Surgery & Recovery — What to Expect
Appendicitis: Symptoms, Surgery, and What to Expect
A pain that starts near your belly button and slides right. Here's what's happening inside — and why you shouldn't wait.
What Is the Appendix, and Why Does It Inflame?
The appendix is a small, finger-shaped pouch about 3.5 inches long, attached to the start of your large intestine in the lower right abdomen. For most of human history, it was written off as useless. We now know it plays a minor role in the immune system, but here's the thing: your body functions perfectly well without it.
Appendicitis happens when this pouch gets blocked. The culprits are usually hardened stool (called a fecalith), thick mucus, or a bacterial infection. Once blocked, bacteria inside multiply fast. The appendix swells, its blood supply gets compromised, and if nothing is done, it ruptures.
The appendix can rupture within 48 to 72 hours of symptoms starting. That's a tight window — and it's why this condition is always treated as an emergency.
It's the most common cause of acute abdominal surgery worldwide. In the US alone, about 300,000 hospital visits happen every year because of it. It most often hits people between ages 10 and 30, though no age group is completely off the hook.
Symptoms: The Classic Pattern You Must Recognize
Appendicitis has a fairly recognizable progression, but it can be deceptive early on. Many people dismiss the initial pain as gas or indigestion. That's a mistake.
How the pain moves
It typically starts as a dull, crampy ache around the belly button. Over 12 to 24 hours, it migrates to the lower right abdomen and sharpens. Moving, coughing, or taking a deep breath makes it worse. This migration pattern is so characteristic that it has a name: McBurney's point tenderness, referring to the exact spot 2/3 of the way from the belly button to the right hip bone.
That said, pain can sometimes be diffuse, especially in pregnant women, the elderly, or children, who often present atypically.
One detail worth knowing: the order matters. With appendicitis, pain almost always comes before vomiting. If vomiting started first, the diagnosis is more likely to be something else like gastroenteritis.
Red Flags — When to Go to the ER Immediately
Sudden, severe abdominal pain that spreads across the whole belly (could signal rupture) — a fever above 103°F (39.4°C) — a rigid, board-like abdomen that's extremely tender to touch — or pain that briefly improved then came back much worse. That "improvement" can actually mean the appendix just ruptured, which temporarily relieves the pressure, only for peritonitis to set in.
A ruptured appendix is a surgical emergency. The complication rate jumps from roughly 3% in intact appendicitis to nearly 59% after rupture. Infection spreads into the abdominal cavity (peritonitis), and from there into the bloodstream — which can be fatal if treatment is delayed.
Do not eat, drink, or take pain medication before getting evaluated. Pain meds can mask the symptoms your doctor needs to assess accurately. Same goes for heating pads and laxatives.
How Doctors Diagnose Appendicitis
There's no single definitive test. Doctors piece together the picture using history, physical exam, and investigations.
Physical exam findings
McBurney's point tenderness is the classic finding. Doctors also check for Rovsing's sign (pain in the right lower abdomen when the left side is pressed), psoas sign (pain on extending the right hip, suggesting a retrocecal appendix), and rebound tenderness. A rigid belly suggests peritonitis.
Blood tests
A raised white blood cell count (leukocytosis) supports the diagnosis but isn't specific. CRP is usually elevated. Normal bloods don't rule out appendicitis.
Imaging
Ultrasound is preferred first in children and pregnant women (no radiation). CT scan is more accurate overall and is the go-to imaging for adults when the diagnosis is uncertain. MRI is sometimes used in pregnancy when ultrasound is inconclusive. Imaging helps confirm the diagnosis and rule out conditions like ovarian cysts, ectopic pregnancy, or kidney stones that can mimic appendicitis closely.
The Alvarado score (combining symptoms, signs, and labs) is a useful bedside tool to stratify risk. A score of 7 or above has a high probability of appendicitis. Scores of 5–6 warrant imaging. Below 5 — watch and reassess.
Surgery: What Actually Happens
The standard treatment is surgical removal of the appendix, called an appendectomy. Surgery needs to happen within 24 hours of diagnosis to prevent rupture. There are 2 main appro
