Hi, I’ve just noticed this morning small clusters of red bumps on my both arms. The bumps are red and itchy, similar to mosquito bites, only smaller and they are spread across my arm in small clusters of like 15-20 of them. They are not red when I’m not irritating them or scratch, so I’ve been trying to figure out what might be the cause and can’t really say they look like scabies or shingles.

I’ve had chicken pox, so I know it’s not that. Is it possible that some allergy to like detergent or perfume causes this type of rash? If not, what else might be causing it?

Thanks for your replies, Megan
