Why do your abs hurt when you sneeze?

When you sneeze, your abdominal muscles contract rapidly to help expel air from your lungs, which can lead to soreness if those muscles are already tense or weak. Additionally, sneezing involves a sudden increase in intra-abdominal pressure, which can strain the muscles in your abdomen. If you've recently engaged in physical activity or have underlying muscle tension, you may feel discomfort in your abs during a sneeze.
