so for the past two months my lower arm by my elbow on the bottom side has been itchy and red. It's all patchy. It's on both arms actually but the one isn't as bad as the other. If i didn't know any better i would think that it was eczema. I have never had that before and I'm not sure if that is something that can just develop all of a sudden. I have been putting lotion on it everyday sometimes several times a day and also my son had eczema when he was little and i have been putting that cream on as well. It really hasn't helped because it is still there. However some days is better then others as far as it not being as itchy and or not looking as patchy.it's really weird. any ideas of what it could be?

Thank you,
Erica
