I m drinking 2 to 3 (60 ml peg) since last 25 years, liver function test , kidney fuction test, cholestrol, blood pressure , diabities, all test is normal but since last t 4 to 5 month , mostly in late evening i feel like very itchy skin and once u start itching the intencity of itching increases and all red rashes comes all over the back, hand legs also rashes goes within half an hour. Is this itching and rashes comes due to i drink alcohole ?
