My daughter came home from her fathers with these bumps. On her arms, hands, legs, and cheeks. She was out in the sun most of the day on Sunday, it was the first hot day here. He said he noticed the rash that night. She has sensitive skin so I'm wondering if this was a reaction to the sun and heat? She wore sunscreen and it was applied multiple times. It's not on her back or stomach (where she was covered so they sun couldn't bother it) any idea what this could be?? Bird mites maybe? We have month old chickens who just started going outside during the day since its been warmer. But wouldn't my husband and I have the bites too? Someone please help!!
