Eczema Treatment Care

I developed a small rash on the lower wings of my labia minora. It just itches (no discharge, pain, or sensitivity. Nor are there any blisters or sores). It started during my last period (which ended a couple of days ago). I usually wear tampons in addition to pads but this developed while I was wearing the pad. There were days where I couldn’t change the pad for quite some time so I thought maybe the pad may have irritated the area (what with the rubbing back and forth over the area that has the rash). I don’t want to go to the hospital if I don’t need to. I looked it up and the symptoms I have match something called Contact Dermatitis, and it was said that this was just a very minor rash that just itches, and that it would go away on its own. It didn’t say how to treat it though so I am at a loss here.
