Sun reaction: I am not able to tell you what is causing your rash without a picture and without you giving us further details. We need to know if you were wearing a sleeveless type shirt and if you were out in the sun without using sunscreen. Are you taking any medication that may have caused you to have sun sensitivity ???!!! Please write back . in the meantime if you are uncomfortable you need to see a physician or go to urgent care for treatment and and to find out what is causing a problem. Take care
