Skin RashFrom coming in contact with poison ivy to dealing with a high dose of stress, there are many reasons a rash might appear. Most of the time, a rash will go away on its own without treatment; however, it’s also important to recognize when a rash may warrant turning to a dermatologist for treatment.

What causes rashes?

There are so many reasons why a rash may surface. Rashes may be the result of a bacterial, fungal, or viral infection, or it could be caused by an allergy. Common causes of a rash include,
  • Atopic or contact dermatitis
  • Eczema
  • Pityriasis rosea
  • Hives
  • Insect bites and stings
  • Poison ivy, oak, or sumac
  • Rosacea
  • Measles
  • Ringworm
  • Impetigo
  • Psoriasis
  • Diaper rash
  • Shingles
  • Lichen planus
  • Chickenpox
  • Lupus
  • Scabies
  • Allergy to a drug/medication
How do I treat a rash?

Most rashes are mild, self-limiting, and can be treated on your own without having to turn to a doctor. Some ways to ease a rash and promote faster healing is by,
  • Using only gentle cleansers and soaps that do not contain harsh chemicals or fragrances
  • Avoiding hot water and only using lukewarm or cold water
  • Being gentle when cleansing, bathing, and handling the skin
  • Not covering the rash (let it breathe)
  • Using only unscented products
  • Applying calamine lotion to control itching
  • Using hydrocortisone cream to reduce itchiness, swelling, and redness
  • Not scratching the rash, as this can lead to an infection
When should I see a dermatologist about my rash?

It’s important to recognize when a rash probably requires medical attention. You should schedule an appointment with your dermatologist if,
  • The rash is widespread and takes over most of your body (this could be a sign of an allergic reaction, which requires immediate attention)
  • The rash is spreading quickly and suddenly
  • Your rash is accompanied by a fever (this is often a sign of serious infection)
  • The rash is painful or contains blisters
  • There are signs of infection such as oozing, crusting, or skin that’s warm to the touch
Dealing with a rash that is painful or causing your concern? If in doubt, don’t hesitate to call your dermatologist. We can discuss your symptoms over the phone and determine whether you should come in for a consultation.
