A girl known to me is suffering from severe abdominal pain for about a month now. She takes food only only once in a day and that too hot and spicy. Sonography report says that there is swelling in stomach and liver. Pain gets excruciating when she eats anything hot. Also swelling appears on her hands, feet, face and all body. She tried some tablets, but there is no relief. What is the cause of this ailment and what is the remedy?
