I feel for you because I've been there and done that. I had it in my crotch when I was 8 months pregnant! I have no idea how that happened. I just have to be 100 miles away and it seems like I get it. Anyhow, I once had it as a teenager allover my back and my family was going on vacation to the ocean. I jumped in, screamed from the pain and my poison ivy went away overnight.
