Localized 
pain is confined to or is most intense in
one section of the abdomen.
Localized pain may indicate a more serious problem if:
- The pain comes on suddenly and increases in
severity. Sudden severe pain may be caused by a problem with an
underlying organ .
- Other symptoms develop,
such as nausea and vomiting or fever, after the abdominal pain started. It is
common to have cramping abdominal pain immediately before vomiting or having
diarrhea. However, a more serious problem may be present when nausea and
vomiting start after the onset of abdominal pain.
- Generalized
abdominal pain becomes localized pain. This may mean there is an infection in a
specific organ, such as
appendicitis or
diverticulitis.
