Rash that turns into pimples

Patient: Its been 4 days and still the same right now. At first its like normal rashes red, but after one day it turns into mini pimples like that.Got it on 1st January after a night of heavy drinking (Carlsberg, Guinness, some mojito and few shots of JD) (is this alcohol flush?) and also eating seafood (squid, fish, softshell crabs) (is this allergy?). I also slept at a very cheap motel beside the sea (is this a bug bite? bed bugs?).http://www.ultraimg.com/image/5sxu photo of my rash-pimple
