Yonghwa picked up the clipboard from the front of the patient's bed. "Good morning. How are you? Your head still painful after the surgery?" The patient subconsciously touched the bandage on his head and replied that he was already feeling much better, and Yonghwa advised him to quit drinking. However, the middle-aged patient argued that social drinking wouldn't hurt and said that a few glasses of red wine was acceptable. "What you are doing isn't just social drinking, it's binge drinking.

Everyone had their stares fixated on her as she continued, "A sudden headache, loss of vision and paralysis of the limbs are symptoms of a haemorrhagic . The symptoms of brain tumour are much more complicated. Different tumours have different symptoms. For instance, a frontal lobe tumour may lead to a sudden change in character. So before a thorough examination, we can't tell much."
