help rash

I just noticed a hour ago i had this pinkish/ red looking rash on the inner part of my arm . It doesnt itch, just burns. Now it kind of spread a little from my elbow to my wrist. Its a little bumpy. And i just noticed i have it on my elbow on the other arm also. what can it be?

Could you have brushed up against a plant or something? Maybe touched a really cheap perfume? It sounds like you've come in contact with something that's just irritated your skin. Not like a bite or anything. Keep an eye on it and see if it gets better or worse and if it's still causing you worry, you can see a doctor about it
