About the Symptom
Erythema describes the redness of skin. It occurs with any skin infection, injury or inflammation but may also not be associated with any disease.
Possible Causes
Generally, Red skin can be related to:
- Acute Urticaria
Acute urticaria is a sudden onset of hives that lasts less than six weeks. It is often triggered by allergic reactions to foods, medications, insect stings, or infections. Acute urticaria can affect individuals of any age and typically resolves once the underlying cause is identified and addressed.
- Chronic Urticaria
Chronic urticaria is a condition characterized by the presence of hives (urticaria) that persist for six weeks or longer. It can be classified into two main types: chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIU). CSU occurs without an identifiable trigger and can be associated with autoimmune conditions, while CIU is triggered by specific stimuli such as pressure, temperature changes, sunlight, or exercise. Both types can cause significant discomfort and itching and can affect individuals of all ages.
- Erythema Induratum
Erythema induratum, also known as nodular vasculitis or Bazin disease, is a group of skin conditions related to active or silent tuberculosis. It is a chronic, nodular eruption that usually occurs on the lower legs of young women.
- Varicella (Chickenpox)
- Erythema Multiforme
- Discoid Lupus Erythematosis
- Pityriasis Versicolor
- Eosinophilic Pustular Folliculitis
Related Serious Diseases
Sometimes, Red skin may be related to these serious diseases:
- Drug Rash
A severe allergic reaction that may result in fevers, a severe rash and organ damage in reaction to medications.
- Scrub Typhus

She feels this is what really allows her to help her patients. “There is a lot of problem-solving in dermatology and I like that,” she explains. “It’s also a profession where you can help people quickly and really make a difference in their lives.” | Some of the typical skin problems that Dr. Nori treats include skin cancers, psoriasis, acne, eczema, rashes, and contact dermatitis. Dr Nori believes in using all possible avenues of treatment, such as biologics, especially in patients with chronic diseases such as eczema and psoriasis. “These medications can work superbly, and they are really life-changing for many patients.” | Dr. Nori feels it’s important for patients to have a good understanding of the disease or condition that is affecting them. “I like to educate my patients on their problem and have them really understand it so they can take the best course of action. Patients always do better when they understand their skin condition, and how to treat it.”

User Testimonials for Red skin
Female, 10s
Ubie helped by matching my symptoms to something that was a serious diagnosis. Apart from asking multiple questions it was quite accurate as the dermatologist had a similar analysis. My symptoms included itchy patchy skin with many red rashes, swelling, and irritated skin texture. My dermatologist finally diagnosed me with eczema.
