You can try hydrocortisone, I usually use it when I get some kind of skin irritation. One time I moved into a new place and I guess I had a bad reaction to something there because I had this really bad rash on both of my forearms. I couldn't figure out anyway to get rid of it. Usually I would just scrub it in the shower (bad idea though because that just led to me scratching it). But anywho I remembered that when I was younger and had eczema my doctor gave me hydrocortisone and luckily they sell it over the counter. So I put some on my arms the night before and when I woke up it was completely gone. You can usually find it in the aisle that has the bandaids, and neosporin. ^_^ I'm not a doctor though, but that's just my personal experience with it.
