I have poision ivy all over and it has lasted for about 3 weeks now. Brusing just started this past week. Is it really from scratching? The steriods are not working or the scream that they gave me to clear it up. I clear up in one area and then it spreads to another area. I get the poison when the wind blows - I am highly allergic so I know to steer clear from it. However, the dogs and kids do not. Suffering! :(
