Every time I drink alcohol, even just half a glass (beer, wine, hard liquor) I get red itchy rashes. It start with my cheeks, goes up to my ears ( they feel very hot ) and after goes to my neck, chest, arms. And it's very itchy. Am I allergic to alcohol? Before giving birth to my son, I never had that kind of reaction (my son is now 3). I never drink while being pregnant and I breastfed for 1 1/2 years after so I wasn't drinking.
