most helpful answer if a rash forms on your skin where you have been exposed to it you should see a doctor to have it checked out. the skin rash and itching that some people get from contact with poison ivy is an allergy. so yes if you get a poison ivy rash that means you are allergic to it. some people can come in contact with poison ivy and not get a rash. that's because they're not allergic to poison ivy. but remember as with any allergy you can become allergic at any time. just because you've never had poison ivy doesn't mean that you won't get the itchy rash that comes along with it next time you're exposed. so it's always best to avoid it whenever possible. i would not try rubbing kerosene on my skin knowing how flamable it can be. use white kerosene with a cloth 2-3 daily and stay away from open flames. used it in the 1970's and worked the best. unothadox but works.
am i allergic to poison ivy?
