Your appendix is on the right side of your body, sitting in the lower right portion of your abdomen. Specifically, it’s a small, finger-shaped pouch that sticks out from your cecum, the spot where your small intestine connects to your large intestine. Most people searching this question want to know either out of curiosity or because they’re feeling pain and wondering if it could be appendicitis. Both are worth covering.
How to Find the Exact Spot
The traditional surface landmark for the appendix is called McBurney’s point. You can find it by imagining a line between your belly button and the bony point at the front of your right hip. McBurney’s point sits about one-third of the way along that line, measured from the hip bone. In most adults, that’s roughly 1.5 to 2 inches from that hip bone, landing in the lower right quadrant of your abdomen.
This is the spot where tenderness is most telling during an appendicitis evaluation. If pressing on that area produces sharp pain, especially when the pressure is released, it’s one of the strongest physical signs that the appendix is inflamed.
When the Appendix Isn’t Where You’d Expect
Not everyone’s appendix is in the standard position. The appendix can sit behind the colon rather than in front of it, which changes where pain shows up. In rare cases, a condition called situs inversus causes all the body’s asymmetric organs to be mirrored, placing the appendix on the left side instead. Situs inversus occurs in roughly 1 in 5,000 to 10,000 people and accounts for more than 67% of left-sided appendicitis cases. If you’ve been told you have situs inversus, appendicitis pain would appear on your left.
During Pregnancy
Pregnancy shifts the appendix significantly. As the uterus grows, it pushes the cecum and appendix upward and rotates them counterclockwise. By the third trimester, about 72% of pregnant patients have their appendix located in the right upper region of the abdomen, not the lower right. Another 22% have it sitting in the right middle region. Only about 5% still have the appendix in its usual lower-right position by late pregnancy. This is one reason appendicitis during pregnancy can be harder to recognize: the pain shows up higher than expected.
What Appendicitis Pain Feels Like
Appendicitis doesn’t usually start with sharp pain in the lower right. It typically begins as a dull ache around the belly button, easily mistaken for a regular stomachache. Within a few hours, the pain migrates to the lower right quadrant and becomes sharper and more constant. This migration pattern is one of the most distinctive features of appendicitis.
The underlying cause is usually a blockage inside the appendix. The blockage leads to swelling, infection, and eventually restricted blood flow. If untreated, the appendix can burst, spilling infection into the abdominal cavity.
Several physical signs help distinguish appendicitis from other causes of abdominal pain:
- Rebound tenderness: Pressing on the sore area hurts, but releasing the pressure hurts even more.
- Pain when coughing: A cough or sudden movement intensifies the pain in the lower right abdomen.
- Left-side pressure, right-side pain: Pressing on the lower left side of the abdomen produces pain on the lower right side.
- Hip-related pain: If the appendix sits behind the colon, extending or rotating the right hip can trigger pain because of irritation to the muscle that runs along the spine and hip.
Right Side Pain That Isn’t the Appendix
Plenty of other things live in or near the lower right abdomen. Ovarian cysts, kidney stones passing through the right ureter, inguinal hernias, and inflammatory bowel conditions affecting the end of the small intestine can all produce pain in that same quadrant. The key differentiators for appendicitis are the belly-button-to-lower-right migration pattern, pain that steadily worsens over 12 to 24 hours rather than coming in waves, and tenderness that spikes when you release pressure on the area.
If you’re pressing on McBurney’s point and feeling significant tenderness, especially with rebound pain or pain that gets worse when you cough, that’s a combination worth getting evaluated promptly. A ruptured appendix turns a straightforward surgical problem into a much more serious abdominal infection.
