Hives vs Bug bites: What Are The Differences?

In cases where vasculitis ( inflammation of the blood cells) may be the cause, your allergist may conduct a skin biopsy and send it to a specialist to examine under a microscope.

Contact dermatitis is a skin rash that occurs when the skin comes into contact with an irritant or allergen. Common causes include plants, chemicals, jewelry, and cosmetic fragrances.
