Skin Allergy

I'm suffering for skin allergy started monday morning.
Firstly my hand come out in blotches & rash and it tend to be very ITCHY!
Never care about it because i tho i might because i have taken beer on Sunday night.Eventually, my hand and leg is getting serious and appear more rashes.
It DO disrupting my sleeeping time! i cant sleep well the whole night just because this so call '' skin itchy'' GRRRR!!!

This is actully my first time and im not sure i got infected becos of beer, salmon or shisha... Doctor said that the cause is eczema but it doesnt look like it! =[

i cant accept if im allergic to beer & seafood. HOPEFULLY is because of the shisha lahh~~~
