For spleen, upper left abdominal pain, for the appendix pain in the right abdo. near the navel. Seek medical care regardless.
Abdominal pain (or stomach ache) is a common symptom associated with transient disorders or serious disease. Diagnosing the cause of abdominal pain can be difficult, because many diseases can cause this symptom. Most frequently the cause is benign and/or self-limiting, but more serious causes may require urgent intervention.
Acute abdomen can be defined as severe, persistent abdominal pain of sudden onset that is likely to require surgical intervention to treat its cause. The pain may frequently be associated with nausea and vomiting, abdominal distention, fever and signs of shock. One of the most common conditions associated with acute abdominal pain is acute appendicitis.
Rupture of the capsule of the spleen, an organ in the upper left part of the abdomen, is a situation that requires immediate medical attention. The rupture of a normal spleen can be caused by trauma, such as a motor vehicle accident.
The appendix (or vermiform appendix; also cecal [or caecal] appendix; also vermix) is a blind-ended tube connected to the cecum, from which it develops embryologically. The cecum is a pouchlike structure of the colon. The appendix is located near the junction of the small intestine and the large intestine.
The term "vermiform" comes from Latin and means "worm-shaped".

Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing, is a sign of appendicitis. If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis.
In acute appendicitis, palpation in the left iliac fossa may produce pain in the right iliac fossa.
