A 20-yeаr-оld cоllege student hаs hаd abdоminal pain for 3 days. It started at his umbilicus and was associated with nausea and vomiting. He has been unable to find a comfortable position. This morning, the pain became more severe and constant. He now hesitates to walk because any motion makes the pain worse. The pain is localized to the right lower quadrant just below and anterior to the iliac crest. What is the most likely reason for his pain?
