👉 Hernia is a common condition in which one of the two abdominal muscles, called the diaphragm or intercostal muscle, fails to contract fully and protrudes through the space between the organs. This can cause pain, discomfort, and sometimes even vomiting. It's often caused by an injury or strain to the diaphragm, or it may be due to a hernia of other types like a herniated disc or a rupture of the abdominal aorta.
