Rash Q & A

What is a Rash?

A rash is a general term for any change in the texture, color, or quality of your skin. A rash can be a simple irritation, or it can be a sign of more serious underlying issues that may require monitoring or treatment.

Different types of rashes are characterized by their location, distribution, appearance, and timing of onset.

What are the Symptoms of a Rash?  

Rashes vary widely and may involve a variety of symptoms, depending on the underlying cause. Symptoms may include:

  • Itchiness
  • Redness
  • Warmth
  • Swelling
  • Tenderness
  • Small bumps
  • Blisters
  • Dry or scaly skin
  • Discoloration


These symptoms may be generalized or localized, and they may come on suddenly or appear gradually over time.  

What Causes a Rash?

As part of a comprehensive assessment, your dermatologist takes a health history and performs an exam of your skin. Using this information, they can determine an underlying cause and create an individualized treatment plan for you.

A rash can develop for a number of reasons, such as:

  • Food allergies
  • Insect bites
  • Heat
  • Poison ivy or oak
  • Contact dermatitis
  • Athlete’s foot
  • Yeast infection
  • Eczema or psoriasis
  • Acne
  • Shingles
  • Chronic skin conditions
  • Scarlet fever


Depending on the cause, some rashes are no need for concern and resolve on their own; others require immediate intervention.

When is a Rash Something to Worry About?

Your dermatologist should evaluate your rash as soon as possible if you have certain symptoms that may indicate a serious condition, such as:

  • Thick, yellow or green drainage
  • Sudden onset, especially after eating
  • Painful itching
  • Generalized distribution
  • Eye or mouth swelling
  • High fever
  • Breathing difficulty  


If your rash causes difficulty breathing, comes on suddenly, or is accompanied by a fever, seek emergency medical attention immediately, as this could indicate a severe allergic reaction.

If you have any other concerning symptoms, or if your rash has not resolved on its own, contact Mohs Surgery & Dermatology Center for a thorough exam, diagnosis, and specialized treatment plan. Call or book an appointment online today.
