Rashes Q & A

What Commonly Causes a Skin Rash?

Skin rashes represent a very broad range of symptoms that arise from multiple causes. The most common rashes are those that develop when your skin comes into contact with an irritant or allergen.

Rashes are also caused by medications, a bacterial, viral, or fungal infection, and a wide variety of medical conditions.

These are only a few possible types of rashes representing different causes:

  • Cellulitis (bacterial infection)
  • Ringworm (fungal infection)
  • Herpes virus (shingles)
  • Lupus erythematosus (autoimmune disease causing a butterfly rash on face)
  • Lichen planus (inflammatory rash caused by autoimmune disease or medications)


Some rashes have a unique, identifying appearance, but more often, rashes from different causes share similar characteristics. In other words, getting to the root cause of a rash requires the expertise of the team at Vanguard Dermatology.

What Rash Symptoms Might I Develop?

Most rashes are itchy, painful, and cause one or more of the following:

  • Red, swollen patch
  • Raised, red bumps
  • Red welts (hives)
  • Dry, scaly patch
  • Fluid-filled blisters
  • Lesions that bleed or ooze


Your rash may stay confined to a localized area or spread over your body.

What are the Most Common Allergic Skin Rashes?

When your rash is caused by an allergy, your symptoms are triggered by an immune response to the allergen. The two most common allergic skin conditions are:

  • Allergic Contact Dermatitis: When you have allergic contact dermatitis, you develop a red, bumpy, itchy rash after your skin comes into contact with an allergen. Poison ivy, nickel, latex, and wool frequently cause an allergic rash.
  • Hives (Urticaria): These red, itchy welts may be triggered by food allergies, pollen, and allergic reactions to medications. They also form in response to nonallergic infections.


What is the Treatment for Rashes?

The first step is to determine the underlying cause of your rash. In addition to reviewing your medical history and a careful examination of the rash, your doctor at Vanguard Dermatology may perform lab tests to rule out underlying health conditions or a skin patch test to identify allergens.

Your customized treatment depends on the cause and severity of your rash. Treatment options range from medications to relieve symptoms and treat an underlying health problem to antibiotics, allergy shots and wound care.

If you have a rash that’s severe, worsens, or lasts several days, call Vanguard Dermatology or book an appointment online.
