From 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
