 [ Symptoms ] am i allergic to poison ivy [ Disease ] 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 is because they are not allergic to poison ivy but remember as with any allergy you can become allergic at any time just because you have never had poison ivy does not mean that you will not get the itchy rash that comes along with it next time you are exposed so it is 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 is and worked the best unothadox but works
