Rash on my arm

[Ms.Honey]

This morning at work all of a sudden my forearm was itchy, and it got all bumpy, and all day now I’ve had a pink raised rash. I can’t tell if it’s gotten worse, but it definitely hasn’t gone away like I was hoping... me being me, I was immediately questioning if it’s petechiae. It’s not. But it brought on a panic attack, which is really extra terrible when I’m at work (no privacy there)
I know it’s probably caused by some allergen?? Has anyone else just had a rash come out of the blue? What could have caused this? I’m scared it will be worse by morning!

I have sensitive skin it seems like that type of stuff happens to me a lot. I would just wash it with whatever soap you use dry it and leave it alone. Just keep an eye on it to make sure that it doesn't start to spread.

I’m allergic to a lot of stuff and frequently get itchy red spots that appear out of nowhere. I usually don’t know what caused them. I dab on some cortisone cream and they usually go away before too long.
