There are different types of side effects that may be experienced by people who have gone through an appendectomy. For example, there are some who may have some allergies because of the medications that they have taken. There are also some who may experience some breathing issues.
For those who have sensitive skin or are more sensitive to infection, they may encounter some infection and inflammation of the incision made. This will make the incision a bit harder and sensitive to cleaning. There are some who experience a ruptured appendix while undergoing the appendectomy. This may cause the abdomen to swell up.
