3 days ago I noticed a bit of stingy itchy feeling on back of neck, along hairline. I then noticed a rash. Day 2 I started feeling same feeling extend to right arm (not shoulder hand, just inner arm). I took Benedryal (spelling?) and thought through food, skin products and whatnot that were new to my system. I had been on road trip, nothing new except climate change. Today, the rash has continued to spread downward, now on torso and hips. No fever, headache, queesy stomach, stiffness, running nose, cough...just rash.
