Get relief from allergy-related rashes in Vernon Hills area with specialist expertise

There are many types of rashes with many different causes. Typically characterized by bumps, itching, and redness, rashes may be attributed to illnesses such as the chicken pox and measles, friction, excessive exposure to moisture or heat, and poison ivy and other plants.

Eczema and hives are rashes that also represent the most common skin conditions, and both are related to allergies. When your immune system mistakenly perceives a substance such as a food, medication, or insect sting as harmful, it attacks the perceived offender by releasing histamines and other chemicals. Skin inflammation is one of the ways your immune system reacts when exposed to an allergen.

While eczema generally manifests as an itchy rash, atopic dermatitis is the most common type of eczema. It is also characterized by dryness and the tendency to blister and ooze should the area be scratched. Triggers include certain foods, animal dander, and dust mites.

A rash caused by contact with certain substances is known as contact dermatitis. Irritants such as detergents, solvents, and adhesives can produce a rash that is more painful than itchy. Nickel, latex, perfumes, and dyes may be problematic and produce itchy, red bumps and blistering.

Hives often start as itchy patches that turn into swollen red welts. They may appear anywhere on the body. Acute hives come and go for a few days or a few weeks at a time while chronic sufferers may have episodes that last for months or even years. Also called urticaria, this common condition has many triggers, including:
  • Food, especially peanuts, eggs, or shellfish
  • Penicillin and other medications
  • Stings or bites from some insects
  • Animal dander
  • Pollen
Environmental factors such as stress can make hives even worse. Since not all skin rashes are caused by allergies, Dr. Noga Askenazi and Eugenia Hahn can determine the cause of your symptoms with tests that include exposing your skin to small amounts of a suspected trigger in a controlled, safe manner to see how the area reacts. Generally, a red bump at the site is indicative of an allergic reaction.
