I believe i have poison ivy?

Itchy ...skin rash: Usually poison ivy allergy appears as itchy, red skin rash with swelling and blisters sometimes. Though there are home remedies; it might be a good idea to see PCP to identify the problem and treat appropriately.

Blisters in patches: Poison ivy is caused by an oily substance that can pass from direct plant contact to your hands or clothes & spred to anything it touches. Itching may start in hours, but the tiny blisters may take a day to come up. Usually linear streaks occur where a tainted finger scratched by chance.Once the oil is washed away, the rash cannot be passed by contact with the skin.

Circumstances: Matter. If you did not work in the garden or somehow got exposed to plants, hiking or so it is not likely that you have poison ivy even though the rash might look like a poison ivy rash. Would suggest having your physician take a look at the rash, if it does not go away in few days.
