What is this itchy pimple like rash on my arms?

Answer by  JennW (342)

Possibly your skin's response to a viral infection. Treat the symptoms with an antihistamine and a topical itch cream - to make yourself more comfortable and make a doctor's appointment.

There are several types of causes for itcy pimple like rashes on one's arms. Poison Ivy, Sumac, and Oak can cause bubbly rashes on whatever skin came into contact with the poisonous plants. Swimmer's Itch or Heat Rash are also possible. Even having a spider leave a trail of bites while you're sleeping can cause a rash on your arms.

This is most likely an allergy to soap or laundry soap. Too much direct sun exposure can make it worse. You should see your doctor if it lasts more than a few days.

I don't know the names for them but it's either one of two things. If you've been out in the sun or tanning it's caused by the UV rays and any sensitive formula lotion will help. If you haven't been in the sun, it might be rosatia, and the sun will cure it, go tanning.

Go to the doctor and have them check it out, it may be anything from acne to something more serious, like Keratosis Pilaris. Google it for more info.

It could be Rosacia, it can cause redness and pimple like bumps. Or you could just be allergic to something.
