There is no definitive answer to this question as the location of the appendix can vary from person to person. However, it is generally believed that the appendix is located on the lower right side of the abdomen.
Appendicitis usually begins with a discomfort in the middle of your abdomen (abdomen) that may go away and return. The pain moves to your lower right-hand side, where most appendices are found, and becomes constant and severe within hours. Squeezing or walking may aggravate the discomfort.
