Red rash on the body that does not itch?

Recently, I developed some oval-shaped, dry, cracked lesions on my limbs and back.
After seeing a dermatologist, I was diagnosed with eczema.
After using topical medication and taking oral medication, there was improvement (approximately two weeks).
However, the lesions have not disappeared and resemble dried scars.
After another two weeks, I noticed that larger areas of non-itchy red rashes have appeared on my limbs, back, and shoulders.
Could this still be eczema? Additionally, after the initial diagnosis of eczema, I used a white topical medication, which caused my skin to develop large areas of deep brown, cracked dryness, which was quite alarming.

Hello: Based solely on the textual description, it is not possible to definitively diagnose eczema.
However, the presence of extensive deep brown, cracked skin after applying medication may indicate excessive dryness and a lack of lipids, potentially resulting in xerotic dermatitis.
It is recommended to apply more moisturizing lotion, cream, or petroleum jelly to improve the condition.
Thank you!

More Info

Understanding non-itchy red rashes can be quite challenging, especially when previous diagnoses like eczema (or dermatitis) are involved. Based on your description, it seems that you have experienced a progression of skin issues that initially responded to treatment but later evolved into a different presentation.
Eczema, or atopic dermatitis, is a common skin condition characterized by dry, itchy patches of skin. However, it can present in various forms, and not all eczema is itchy. In your case, the appearance of oval-shaped, dry, red patches that have now expanded could suggest a few possibilities.

1. Eczema Flare-Up: It's possible that you are experiencing a flare-up of eczema. Eczema can sometimes present as red, inflamed patches that may not itch, especially if the skin barrier is compromised. The initial treatment may have reduced the inflammation, but if the underlying triggers (such as allergens, irritants, or stress) are still present, the condition may recur or worsen.

2. Contact Dermatitis: If you have been exposed to new products (soaps, lotions, detergents, etc.), it could lead to contact dermatitis, which can manifest as red rashes that may not always be itchy. This type of dermatitis occurs when the skin reacts to an irritant or allergen.

3. Psoriasis: Another possibility is psoriasis, which can also present as red, scaly patches on the skin. Psoriasis is typically characterized by well-defined borders and can sometimes be mistaken for eczema. It is usually not itchy, but it can be uncomfortable.

4. Other Skin Conditions: There are other skin conditions that can cause non-itchy red rashes, such as pityriasis rosea or even fungal infections. These conditions can sometimes mimic eczema but have different underlying causes and treatment approaches.

Regarding the deep brown, cracked appearance of your skin after using the topical medication, this could be a result of several factors:
- Medication Reaction: Some topical treatments can cause skin irritation or a reaction, leading to discoloration or dryness. It's essential to inform your healthcare provider about this reaction, as they may need to adjust your treatment plan.

- Skin Barrier Damage: If the skin becomes overly dry or irritated, it can lead to cracking and discoloration. This is particularly common in conditions like eczema, where the skin barrier is already compromised.

Given the changes in your skin condition, it is crucial to follow up with your dermatologist. They may recommend a different treatment approach, such as:
- Moisturizers: Regularly applying a good moisturizer can help restore the skin barrier and reduce dryness.

- Topical Steroids: If inflammation is present, a different class of topical steroids may be necessary to manage the flare-up effectively.

- Patch Testing: If contact dermatitis is suspected, patch testing can help identify specific allergens that may be triggering your symptoms.

In summary, while your symptoms may still relate to eczema, the changes in your skin's appearance warrant further evaluation. A dermatologist can provide a more accurate diagnosis and tailor a treatment plan that addresses your specific needs. It's essential to communicate all your symptoms and any changes in your skin condition to ensure you receive the best care possible.
