am i allergic to alcohol?

yesterday, i drank 2 bottles of iceland vodka mix (4.8% alcohol content) at 5 pm, then i fell asleep. i woke up at 9 pm because my back felt very hot and itchy. When i looked at my back, the pores in my back were open and enlarged 3 times their normal size, and there was a slighttt rash. the itching hasnt gone away until now. could I be allergic to alcohol? i cant go to the doctor yet, money is tight rn lol
