I have a rash on my chest, back, neck, below the naval. It is not on my arms or legs. It is red and blotchy, and on both sides of my body. I have noticed when I take a shower or out in the sun, it becomes more inflamed. It really is not itchy, just sometimes. It is red, and some are raised above the skin. It is not full of pus. I have had it about 3 days. I am an adult woman over 50. When I was a girl, I had chicken pox, measles, and mumps. Thanks
