I have been n the sun over the last few weeks a rash similar to poison ivy n itchy. It seems like the sun irritates n makes it worse. Could this b sun poisoning? If so how do I treat n protect from it continuing to intensify?

Many people are allergic to the sun. Get a cortisone spray and wear long sleeved loose THIN cotton shirts, and a sun hat. Spray sun tan lotion on exposed parts that have to be in the sun. And of course try to stay in the shade.
