In brief: Sun causes rash

If you go out in the sunlight and develop a rash you have photosensitivity.
If you are unsure, uncover a small part of your body - say the lower half of one arm, for 5-30 minutes in the sunlight while keeping the rest of your skin clothed. To be very careful try five minutes first. If no rash appears try 10 minutes the next day gradually increasing to 30 minutes. Good luck.
