I sympathize with you, for
I have the same problem. About 7 years ago, my husband and I went on our honeymoon to Florida. Up until then, I had no problems being out in the sun. I am Italian, and have a naturally darker skin tone, so I would tan beautifully. While on our honeymoon, I started breaking out in this rash on my nose, then my cheeks, my arms, and then my chest. The itching was horrible.
