[briannekyle]

Hi, im a male and so conscious about what is happening to my body. I am currently suffering on alopecia areata or a spot balding that was after i got flu that last for 3 days. And i have this palm size brown at my back for two years and just thought that it maybe skin pigmentation so just ignored it. But when i suddenly drank jack daniels and vodka it turned to red became bigger. So i am wondering if this two cases alopecia and back rash are related to each other. Or if not please some one help to distinguish.what type of rash i got. I have been dealing with it for a month now. putting anti fungal cream coz a friend said it maybe tinea. It turns black in color now. Please bare with the picture.

FDE in ocassions just an erythema in a coin shaped area.

Hi, comment appreciated. But didnt have any blisters on it, didnt even itch or burn. When i got up in the morning after drinking and took a shower thats the time i saw them while drying up my body. I touched them and they were warm. And got a sore throat within the same day i am wondering that they could be hives. But the question is why are they still there. Im not yet diagnosed planning to go to a doctor or to dermatologist but to my home country maybe coz im currently in the other country.

Possibly a Fixed Drug Eruption(FDE) to alcohol or colorants in vodka.
