Hives help!

Been a heavy drinker for a long time. About 7 years and the last few have been about a half a bottle of 1.7L maybe more a day. With the occasional only few shots certain days. Been trying to quit and the last few days I’ve been breaking out in crazy hives. Only in the mornings around 5 or 6 hours after my last drink. Stopped cold turkey a few days ago and they stopped. Today I used rubbing alcohol on a cut on my foot and immediately my hands started to swell and now have hives back running up the same leg. Have I developed an alcohol allergy?
