Hi, my name is JoAnn from NV., i have lived in my home for ten years and for the last 5 summers I have suffered from the 2 arm rash, bumps, itchy and on fire. It starts in June and ends in Sept. This year after talking so much about it someone finally suggested Benedryl, it helps but I have to take it every 4 hours or it comes back immediately, the only thing I can think is that I change plants in the yard everyyear, so I am wondering if plants, have anything to do with this, it always starts within an hour of when I come home.  The one thing I haven't tried is the poison oak lotion along with the pills, i will try it, I am so relieved to know I am not the only one with this.  Thanks for sharing...
