Rashes Treatment

Rashes are one of the most common reasons patients visit a dermatologist—and for good reason. A rash can appear suddenly, worsen quickly, or linger despite home treatments. At Knight Dermatology, we specialize in diagnosing the root cause of rashes and providing personalized treatment to relieve discomfort and restore healthy skin.

Whether your rash is itchy, painful, spreading, or simply not improving, our board-certified dermatology team is here to help.

What Is a Rash?

A rash is any change in the skin’s color, texture, or appearance. Rashes may appear as redness, bumps, scaling, blisters, welts, or patches of irritated skin. They can affect a small area or spread across the body and may be accompanied by itching, burning, pain, or swelling.

Because many skin conditions look similar, an accurate diagnosis by a dermatologist is essential for effective treatment.

Common Types of Rashes We Treat

We diagnose and treat a wide range of acute and chronic rashes, including:

• Eczema (Atopic Dermatitis) – Dry, itchy, inflamed skin that may flare periodically
• Contact Dermatitis – Skin reactions caused by allergens or irritants such as soaps, metals, or plants
• Psoriasis – Chronic autoimmune condition causing thick, scaly patches
• Hives (Urticaria) – Raised, itchy welts often linked to allergies or immune reactions
• Fungal Rashes – Including ringworm, athlete’s foot, and yeast infections
• Viral Rashes – Such as shingles or viral exanthems
• Bacterial Skin Infections – Including impetigo and cellulitis
• Heat Rash – Blocked sweat ducts causing small, irritated bumps

If you’re unsure what’s causing your rash, we can help identify it.

When to See a Dermatologist for a Rash

You should schedule a dermatology appointment if your rash:

• Lasts longer than one to two weeks
• Is spreading or worsening
• Causes significant itching, pain, or swelling
• Is accompanied by fever or other symptoms
• Involves the face, genitals, or eyes
• Keeps returning despite treatment
• Is affecting sleep or daily activities

Early evaluation often leads to faster relief and prevents complications.

How We Diagnose Rashes

At Knight Dermatology, we take a thorough and thoughtful approach to diagnosing rashes, which may include:

• Detailed medical and exposure history
• Visual skin examination
• Dermoscopy (magnified skin evaluation)
• Skin swabs or cultures (when needed)
• Patch testing for allergic reactions
• Skin biopsy for unclear or persistent cases

Our goal is to identify the underlying cause—not just treat symptoms.

Rash Treatment Options

Treatment depends on the type and severity of your rash. Your personalized care plan may include:

• Prescription topical creams or ointments
• Oral medications (antihistamines, antibiotics, antifungals, or anti-inflammatories)
• Medicated washes or moisturizers
• Lifestyle and skincare recommendations
• Trigger identification and avoidance strategies
• Long-term management plans for chronic conditions

We focus on relieving symptoms quickly while supporting long-term skin health.
