Suggest Treatment For Rashes On Face, Back And Chest Area

I m noticing for three days now a rash on my face, chest area, back and lower back area. Not into my legs yet. I travel a lot, and was just rolling around in the grass in NC (I m a photographer of military stuff) all last week. I noticed rash on my face while there, now it seems to have spread. I don t generally get poison ivy or oak, I m in contact with that stuff all over the country.....never been a problem. Also experience mild kidney area discomfort, lack of energy and aches (not that bad, but not normal)....
