Appendicitis can be applied with a hot water bag. The treatment of appendicitis can be divided into conservative treatment and surgical treatment. The use of conservative treatment methods such as hot compresses, anti-inflammatory and physiotherapy can only temporarily control the condition, but cannot cure it. Appendicitis is prone to recurrent attacks when triggered by excessive fatigue, low immunity, irregular eating, eating cold and irritating foods, etc. It is recommended to develop good habits, avoid overexertion, and exercise properly to increase resistance. If the diagnosis of appendicitis is clear, the principle of treatment is to perform surgery to remove the diseased appendix, which can achieve the purpose of radical cure.
