Skin rashes can be caused by many different factors, including infections, allergens, immune system disorders, medications, and heat.

Different types of rashes include:

  • Eczema causes intense itching with the most common type being atopic dermatitis 
  • Contact dermatitis is triggered by touching something that causes an allergic reaction
  • Seborrheic dermatitis (sometimes called scalp eczema) causes intense scalp itching
  • Fungal infections can result in jock itch, athletes foot, and ringworm
  • Bacterial infections can start small but then spread throughout the body.
  • Hives have many triggers such as foods, extreme heat or cold, drugs, insect bites, and illnesses
  • Herpes simplex and oral herpes cause cold sores and little blisters on your lips
  • Shingles causes an outbreak of a painful rash or blisters on the skin. 


    Rashes should be evaluated and treated by your primary care provider. While some rashes do not require urgent attention, if a rash comes on suddenly with the following symptoms, you should contact your provider immediately or go to an urgent care or emergency room promptly:

    • A rash is all over your body
    • Fever accompanies the onset of your rash
    • The rash is sudden and spreads rapidly
    • The rash begins to blister and is painful or infected

    Some infections or diseases cause rashes, including:

    • Shingles 
    • Chickenpox 
    • HIV
    • Measles
    • Syphilis
    • Roseola
    • Lyme Disease
    • Sepsis
    • Candida 

    For some contact rashes, self-care habits include avoiding harsh soaps and laundry detergents and applying medicated anti-itch creams. Treatments for a rash can be multifaceted. Your provider will evaluate your particular reaction and recommend the appropriate ongoing medications, daily habits, and treatments.
