### input:
Hi I am from Asia, male and of age 34. My wt is 68kg and ht is 1.65m, with no known health problems.My issue is my allergy reaction after drinking alcohol. I have rashes on my back, the rear of my arms, my torso and back of my neck. These rashes are small little red dots, and they are really painful when I sweat. Typically takes about a week before I get well. I came across articles on miliaria and after seeing pictures and reading of symptoms, sounds exactly like what I have! So question is if miliaria can indeed by triggered by consuming alcohol? And if indeed so, can I conclude I am actually not allergic to alcohol, but merely that my skin was unable to handle the heat involved with drinking, or that my pores are clogged? Id like to know that these rashes are limited to my skin and not a symptom of some bigger problems internal to the body. Lastly, please do advice if there is something I can do to prevent these rashes.. They are rally painful (like needles poking) when I sweat, which is really often here in hot and humid Singapore.Thanks for all your kind advice.Alex

Alcohol causes vasodilation of small blood vessels and capillaries and sometimes bursts these capillaries under skin leaving behind broken capillaries and red spots.

The best way to cure allergy is avoidance of contact with allergen rather than taking antiallergic
