Yes, it’s possible to have appendicitis without fever, especially in the early stages. However, as the infection progresses, a mild to moderate fever usually develops. Lack of fever doesn’t rule out appendicitis.

Important Notes

• Early appendicitis: pain and nausea may occur before fever.
• Advanced stage: mild fever (99–101°F) often appears.
• Diagnosis depends on the pain pattern, not just body temperature.
