Pain at McBurney's point is the characteristic of which disease?

Correct option is B

Ans. (b) Appendicitis
Explanation:
McBurney’s point is a specific anatomical location on the abdomen, one-third the distance from the anterior superior iliac spine (ASIS) to the umbilicus, on the right lower quadrant (RLQ).
Pain at McBurney’s point is a classical sign of acute appendicitis, indicating inflammation of the appendix.
Why is McBurney's point important in appendicitis?
1. Early Sign:
· Initially, pain in appendicitis starts as a dull, vague pain around the umbilicus (due to visceral innervation).
· As inflammation progresses, the pain shifts to McBurney’s point in the RLQ (due to somatic innervation of the peritoneum).
2. Rebound Tenderness:
· Pressing on McBurney’s point may not cause immediate pain, but sudden release leads to sharp rebound tenderness, a sign of peritoneal irritation.
3. Associated Symptoms:
· Nausea, vomiting, fever, and leukocytosis (high WBC count) are common findings in appendicitis.
Why are the other options incorrect?
1. Jaundice → (Incorrect Choice)
· Jaundice is caused by liver dysfunction or biliary obstruction, leading to yellowing of skin and eyes, but not pain at McBurney’s point.
2. Peptic Ulcer → (Incorrect Choice)
· Peptic ulcers cause epigastric pain (upper central abdomen), often relieved by eating.
· No relation to McBurney’s point.
3. Gastritis → (Incorrect Choice)
· Gastritis presents with epigastric pain, bloating, nausea, and vomiting.
· It does not cause localized RLQ pain.
