What Is Causing My Rash?

It can be difficult to tell one rash from another without medical training. However, rashes can vary widely in their appearance, the extent to which they cover your body, and how long they last, so it’s important to get medical advice if you are experiencing skin issues. Dr. Elizabeth Fahrenbach and Dr. Joanna Jaros are dermatologists at North Branch Dermatology in Chicago, IL. They are dedicated to providing all their patients with the best possible skincare. If you have a rash that is troubling you, they will be happy to give you an examination and find the appropriate treatment.

When You Should See a Doctor

Chicago residents should seek advice from our dermatologist if:

• The rash covers a large area of your body.
• A fever accompanies the rash.
• The condition is spreading quickly.
• Your skin begins to blister.
• The rash is infected.

Common Causes of Skin Rash

• Contact dermatitis: This rash is caused by exposure to a substance that causes skin inflammation. Detergents, solvents, rubbing alcohol, or fertilizers may trigger contact dermatitis.
• Poison ivy: The chemical urushiol found in the leaves of poison ivy, poison oak, or sumac can cause a rash when it comes into contact with the skin.
• Hives: This is a widespread rash often triggered by food allergies, medications, or insect bites.
• Psoriasis is an autoimmune disorder that causes plaque to build up on the skin, giving it a crusted appearance. The skin may also crack and bleed.
• Shingles: Anyone who has previously had chickenpox can develop shingles, though the virus's trigger is unknown. It causes a blistering rash that can be very painful.
