He must see a general physician if he has
chest pain. Not only the liver, cardiac conditions can also cause right upper quadrant pain. The AST/ ALT values appear normal or only slightly high, but in alcohol users the values do not reflect the liver condition reliably.
It is best to stop alcohol use. But if he is using alcohol regularly (more than 180 ml of hard liquor per day), it is good to
consult a psychiatrist who will give medications for safe
detoxification. Without medication for detoxification, alcohol withdrawals can be complicated in those who are addicted to it.
The signs of addiction to alcohol are the appearance of
withdrawal symptoms on stopping alcohol use. Withdrawal symptoms are: tremors, sleep disturbance, irritability or anxiety, sweating; and in severe cases seizures/ fits/ convulsions or even
delirium (talking irrelevantly and talking about imaginary people/ objects). If he has had withdrawal symptoms in the past, it is a must to seek detoxification from a psychiatrist.
