What symptoms show up after poison ivy exposure?

Itchy rash. Typically one gets a very itchy blistering rash in the areas which contacted the poison ivy. But one can even transfer the oils to other parts of the body if not careful. Scratching makes things worse so don't do it! some people don't react; they're very lucky! and if you wash the oils off quickly (within 15 minutes), you may not react. Use cool water and good gentle soap.
