I have two allergies that cause the same reaction: oranges and latex. They cause me to get a rash on the back of both hands. My latex allergy developed very recently, in November. Two days ago I went to the gym and got the familiar rash. I'm not sure what caused it. My orange allergy seems to manifest quickly, but latex has taken longer in the past. I did not have oranges though, so something in the gym may have had latex in it. Could my allergy be getting worse? How can I treat it?
