If you think you have appendicitis, don’t wait to see if it gets better on its own. The risk of your appendix rupturing increases significantly after 48 hours from when symptoms start, so getting to a doctor quickly matters. In most cases, that means heading to an emergency room, especially if your pain is severe, sudden, or making it hard to move, eat, or drink.
How to Tell if It Might Be Appendicitis
Appendicitis has a distinctive pain pattern that sets it apart from a stomach bug or food poisoning. It typically starts as a vague, hard-to-pinpoint ache around your belly button or upper abdomen. Over the next several hours, the pain migrates to the lower right side of your abdomen and becomes sharper and more localized. This progression from dull and central to sharp and right-sided is one of the most recognizable signs.
Other symptoms that often accompany the pain include nausea or vomiting (usually after the pain has already started), loss of appetite, a low-grade fever, and the feeling that a bowel movement might help but doesn’t. Many people notice the pain gets worse when they cough, walk, or go over a bump in the car. If pressing on the lower right side of your abdomen and then quickly releasing causes a sharp spike of pain, that’s a strong signal of inflammation in the area.
Not everyone follows the textbook pattern. During pregnancy, the appendix gets pushed higher in the abdomen, so the pain may feel like it’s coming from the upper belly rather than the lower right. Young children often can’t describe where the pain is and may just seem generally unwell with a fever and vomiting. Older adults sometimes have milder symptoms that develop slowly, which can delay diagnosis.
Emergency Room or Urgent Care
If your pain is severe enough that it’s hard to stand up straight, function normally, or keep food and water down, go to an emergency room. The same applies if the pain came on suddenly, you have a high fever, or you see blood in your stool or vomit. As one Mass General Brigham emergency physician put it: “If you have any doubt, go to the ER.”
Urgent care can be a reasonable first step if your pain is still in the early, vague stage. Clinicians there can examine you, run initial tests, and determine whether you need to be sent to the ER for imaging. But if the pain is clearly in your lower right abdomen and getting worse, skip urgent care and go straight to the emergency department. Time matters with appendicitis, and the ER has the imaging equipment and surgical teams needed to act fast.
What Not to Do While You Wait
There are a few things that can make the situation worse or complicate treatment if you do need surgery:
- Don’t eat or drink. If surgery is needed, it’s safest to have an empty stomach. Avoid food and liquids unless a doctor tells you otherwise.
- Don’t take laxatives. If you do have appendicitis, laxatives can increase pressure inside the appendix and raise the risk of it bursting.
- Don’t rely on pain relievers to tough it out. Taking something for the pain and deciding to “sleep on it” can cost you valuable hours. Pain that wakes you up or prevents sleep warrants an ER visit that night.
What Happens at the Hospital
Doctors will press on specific areas of your abdomen, check for tenderness, and ask about the timeline of your symptoms. Blood work will look for signs of infection. The key diagnostic step is imaging. A CT scan is the gold standard for adults, with studies showing it catches appendicitis essentially 100% of the time. Ultrasound is used more often for children and pregnant women to avoid radiation, though it’s less sensitive, picking up about 68% of cases. If an ultrasound is inconclusive, a CT or MRI may follow.
The whole process from arrival to diagnosis can take several hours, depending on how busy the ER is. You’ll likely be asked to change into a gown and have an IV placed early on, both for fluids and in case you need to go to surgery.
Surgery Versus Antibiotics
Laparoscopic surgery (removing the appendix through a few small incisions) remains the standard treatment. According to the 2025 guidelines from the World Society of Emergency Surgery, surgery for uncomplicated appendicitis can be safely delayed up to 24 hours without increasing the risk of complications, so there’s no need to panic if the operating room isn’t immediately available.
For uncomplicated cases (meaning the appendix hasn’t ruptured and there’s no abscess), antibiotics alone are now considered a safe and effective option for some patients. This doesn’t mean you treat yourself at home with leftover antibiotics. It means that after proper imaging confirms a straightforward case, your medical team may offer you the choice between surgery and a course of hospital-monitored antibiotics. Some people who choose antibiotics do end up needing surgery later, but for those who want to avoid an operation, it’s a legitimate option to discuss with your surgeon.
Why Timing Matters
A study tracking 255 patients found that the risk of the appendix perforating jumped significantly once symptoms had been present for 48 hours or more. Patients in that group were over four times more likely to experience a rupture compared to those treated between 24 and 48 hours. After 72 hours, surgeries also took longer and were more complex. A ruptured appendix turns a relatively straightforward operation into a more serious situation, often requiring a longer hospital stay, IV antibiotics, and a harder recovery. This is why “let’s see how I feel tomorrow” is a risky strategy with appendicitis.
Recovery After Surgery
Most people go home within a day of a laparoscopic appendectomy. You’ll feel sore around the incision sites for the first few days, and it’s normal for your digestive system to feel sluggish. The traditional advice has been to start with clear liquids and slowly work up to solid food, but more recent evidence suggests the best guide is your own comfort. If you feel ready for solid food sooner, that’s generally fine. Passing gas is often treated as a milestone, but research shows it’s not actually a reliable indicator of how well your gut is functioning. Eat what feels right and don’t force it.
Activity restrictions vary by surgeon. About half of surgeons recommend avoiding contact sports and heavy lifting for two to three weeks after a laparoscopic appendectomy, while roughly one in five don’t impose any formal restrictions at all. Most people return to desk work within a week and resume normal physical activity within two to three weeks. If your appendix ruptured before surgery, expect a longer recovery, potentially a few extra days in the hospital and a more gradual return to full activity.
Shoulder pain in the first day or two after surgery is surprisingly common and not a sign that something went wrong. It’s caused by gas used to inflate the abdomen during the procedure irritating the diaphragm. It passes on its own.
