Hello, My husband and I went to the pacific coast Tuesday of last week and I now have a burning, itchy red rash on one side of my back and under one arm. I remember going for a walk in a woodsy area where there were vines with 3 leaves, looking much like your picture in the header above. The vine had a small berry, looking much like a rasberry. I thought it was pretty and picked the 3 leaves and a berry, took it into the car with me. Later, my back was aching from the long trip, so I reached into my top and rubbed my back. I think this may have been poison ivy, but I don't remember seeing it pictured with a red berry. I complicated matters further by putting a heating pad on the area when I got home, thinking it was hurting from the long trip. Now I can see small blisters forming on the red skin. Can poison ivy have a red berry? Thanks very much.
