Sharp, worsening pain in the lower right abdomen with nausea, loss of appetite, or fever can signal appendicitis, a time sensitive emergency that often intensifies over 12 to 24 hours and can rupture if untreated within 24 to 72 hours. Seek urgent in person care if pain persists or worsens with movement; doctors confirm with exam, labs, and imaging, and most people need quick laparoscopic surgery while some mild cases may try antibiotics. There are several factors to consider. See below to understand more.
A sharp stabbing pain in your lower right abdomen can be alarming. One possible cause is appendicitis, a condition that requires prompt medical attention. While not every stomach ache is serious, appendicitis is not something to ignore.
Understanding what appendicitis is, how it feels, and what to do next can help you act quickly and confidently — without unnecessary panic.
Appendicitis is inflammation of the appendix — a small, finger-shaped pouch attached to the large intestine in the lower right side of your abdomen.
When the appendix becomes blocked (often by stool, swelling, or infection), bacteria can multiply inside it. This causes inflammation, swelling, and pressure. If untreated, the appendix can rupture (burst), which can lead to a serious abdominal infection.
Appendicitis is a medical emergency. It is common and treatable — especially when caught early.
The classic symptom of appendicitis is sharp, worsening pain in the lower right abdomen. However, it doesn't always start there.
The pain usually gets worse over 12 to 24 hours. It rarely improves on its own.
Appendicitis is sometimes described as a "ticking time bomb" because:
That said, most people who seek medical care promptly recover fully. The key is timing.
Appendicitis can happen at any age, but it is most common in:
However, anyone with a lower right abdominal pain that is worsening should consider appendicitis as a possibility.
In children and older adults, symptoms may be less typical. Pain might be less localized or harder to describe.
You should seek urgent medical attention if you have:

If you're unsure whether your symptoms match appendicitis, use a free AI-powered Acute Appendicitis symptom checker to quickly assess your risk and understand what steps to take next.
However, no online tool replaces an in-person medical evaluation.
There is no single test for appendicitis. Doctors use a combination of:
They'll ask:
Doctors check for:
These tools help confirm appendicitis and rule out other causes.
The standard treatment for appendicitis is surgical removal of the appendix, called an appendectomy.
Most people:
In some mild cases, antibiotics may be used instead of immediate surgery. However:
Your doctor will discuss the best option based on your case.
If the appendix bursts:
A ruptured appendix is serious, but treatable. The earlier appendicitis is caught, the simpler the recovery.
Not every sharp lower right abdominal pain is appendicitis. Other possibilities include:
This is why proper medical evaluation is essential. The symptoms can overlap.
There is no guaranteed way to prevent appendicitis.
Some studies suggest that diets high in fiber may reduce risk, but appendicitis can still occur in healthy individuals.
It is not caused by stress or exercise. It is not something you "did wrong."
Most abdominal pain is not appendicitis. But persistent, worsening pain on the lower right side should never be ignored.
If you are unsure whether your symptoms are serious, check them now using this free Acute Appendicitis symptom checker to get immediate guidance based on your specific symptoms.
However, if you suspect appendicitis or feel significantly unwell, seek medical care immediately.
Appendicitis can become life-threatening if untreated. If you have symptoms that concern you — especially severe or worsening abdominal pain — speak to a doctor or visit urgent care or the emergency department right away.
Acting quickly does not mean overreacting. It means protecting your health.
When it comes to appendicitis, early action leads to the best outcomes.
