Got a Rash? Don’t Panic. Here’s When to Go to the ER and What to Expect


An angry red rash spreading across your body can be downright alarming. But try not to panic. While some rashes do require emergency care, many amount to minor skin irritations. This comprehensive guide covers everything from mild rash symptoms to severe reactions warranting a hospital visit. Read on for expert advice on decoding your rash and getting the right care.

What Exactly Causes Skin Rashes?

Skin rashes stem from a wide range of triggers. These include infections, immune system reactions, medications, skin disorders and even cancer. Common culprits behind rashes include:

  • Allergens like foods, pets, plants, latex or metals
  • Insect bites and stings
  • Childhood infections like chickenpox or hand-foot-mouth disease
  • Chronic conditions like eczema, psoriasis and dermatitis
  • Skin infections due to bacteria, fungi or viruses
  • Underlying illness like lupus, lymphoma or scarlet fever
  • Medication side effects or drug allergies

So if you’ve noticed any odd spots, bumps, redness or itchiness on your skin, identifying the trigger is the first step.

When to Head Straight to the Emergency Room

While most rashes clear up easily, some require emergency care. Rush to the nearest ER if you experience:

  • Wheezing, trouble breathing or swallowing
  • Rapid spread across large areas of your body
  • Intense pain or severe swelling
  • Rash associated with head injury or confusion
  • Purple rash spots or bruising (sign of bleeding)
  • Blisters, sores, pus or skin peeling off

These emergency rash symptoms suggest life-threatening allergic reactions, infections or underlying conditions needing immediate treatment. Don’t take chances – get to an ER like Express Emergency Room right away.

What to Expect During Treatment at the Hospital

Arriving with severe rash symptoms, you’ll undergo quick triage so nurses can gauge the urgency. Then an ER doctor performs a head-to-toe physical exam, asking about your medical history and any recent triggers. Based on their suspicions about the cause, the doctor may order blood tests, skin biopsies or allergy tests. These hospital tests help diagnose severe infections, inflammatory diseases or dangerous allergies.

Once the cause is confirmed, ER treatment focuses on minimizing complications and discomfort. Oral antihistamines and soothing creams provide relief from itching and swelling. Antibiotic medications or antiviral/antifungal drugs treat underlying infections. For severe allergic reactions, injections of epinephrine open airways while IV corticosteroids reduce inflammation. The ER staff works quickly to stabilize patients with widespread rashes before addressing any underlying illness.

What to Expect After Leaving the Hospital

Before discharge from the emergency room, you’ll receive instructions on any prescribed medications, follow-up directives and signs to watch for. Be sure to take all medication as directed and closely monitor your condition in the days following hospitalization. Alert your primary care physician about the reactions and schedule any recommended specialist visits. Proper post-hospital care ensures your skin heals while preventing repeat rash flares or reactions.

When to Visit Your Primary Care Office Instead

For milder rashes with limited symptoms, make an appointment with your regular doctor instead. See them promptly if you have:

  • Small localized rashes without pain or itching
  • Previously diagnosed skin conditions flaring up
  • Suspected poison ivy/oak rashes
  • Skin changes along with fatigue or weight loss
  • Rashes lasting over a week without improvement

Your primary care physician can perform exams, order diagnostic tests, provide prescriptions and refer you to dermatologists for specialized care. They’ll also check for underlying illness and monitor symptoms over time.

Rash Prevention Tips

While some rashes relate to inherited conditions and illnesses, you can reduce risks by:

  • Using gentle, fragrance-free skin care products
  • Moisturizing daily and avoiding harsh soaps
  • Wearing breathable fabrics like cotton
  • Identifying and avoiding allergy triggers
  • Treating insect bites promptly to prevent infection
  • Maintaining healthy immune function through diet and lifestyle

Following these basic skin protection tips helps lower chances of uncomfortable rashes and skin reactions.


Don’t take skin rashes lightly – catch them early for the best outcomes. Monitor all spots, bumps and skin changes closely, tracking any accompanying symptoms. React promptly if you notice emergency warning signs, getting emergency care from trusted providers like Express ER. Through accurate diagnosis and proper treatment, even severe skin rashes can be managed for relief.
