Extreme itchy rash all over body/face after hard night of drinking.

I usually drink bourbon at home (good brands) but I went out for an event and got absolutely smashed. I had all types of liquor and towards the end of the night I don’t remember much.

The next day I noticed my forehead was itchy as well as my right forearm. And since then this itchiness has spread to my ears, head, hand, etc

My forehead/scalp has this scaly leathery look and my forearm has bumps all over.

It’s been 2 days since and things have gotten worse.
