Common symptoms of appendix pain, or appendicitis, include pain near the upper abdomen that progresses into sharp pains in the lower right abdomen and abdominal swelling, according to WebMD. Patients may also experience a loss of appetite, nausea or vomiting accompanied by abdominal pain and an inability to pass gas.
Individuals with appendix pain may also exhibit fevers from 99 to 102 degrees Fahrenheit, severe cramps, painful urination and constipation or diarrhea, explains WebMD. Symptoms of an appendicitis are caused by a blockage in the appendix as a result of stool, cancer or foreign bodies. An infection can also cause the appendix to swell as the body works to fight off the illness.
Appendicitis is a result of inflammation of the appendix, which is a 3 1/2 inch tube of tissue that stretches out from the large intestine, notes WebMD. Individuals experiencing appendix pain should consult with a physician immediately. Appendicitis that is not treated can perforate or burst, which causes bacteria and infectious materials to enter the abdominal cavity. Serious inflammation of the abdominal cavity caused by infectious materials can be fatal. The most common treatment for an appendicitis is surgical removal of the appendix, according to Mayo Clinic.
