If a patient with a liver cyst experiences inflammation, and presents with a high fever indicating a relatively severe condition, it is crucial to start treatment with antibiotics to combat the infection as soon as possible. Only after the inflammation is under control can the condition be alleviated.

If the inflammation is not controlled in time, it may develop into a liver abscess, which is a serious and critical condition, thus early treatment is crucial.

Moreover, patients should also avoid spicy and irritating foods in their diet to reduce inflammatory irritation, which can better facilitate the recovery from the condition. The diet should include more protein-rich foods such as eggs, lean meats, and fish, which can provide the necessary energy and improve resistance, beneficial for the recovery of the condition.
