Hello, I wonder how big the liver cyst is? Under normal circumstances, the liver cyst is not too big, and when there is no compression symptom, it generally does not need to be treated. Your symptoms are caused by atrophic gastritis. I suggest you take lansoprazole, amoxicillin and metronidazole orally, pay attention to your diet, avoid catching a cold, and avoid eating cold, spicy and greasy food.
