How do I manage itchy red patches on my arms and neck?

Question

Hi doctor,

I have been experiencing itchy, red patches on my skin for the past two to three weeks. The affected areas include my arms and neck. The skin feels dry and slightly scaly, and the itching worsens at night.

I have not changed any soaps, detergents, or skincare products recently. There is no pain or discharge, but the redness increases after sweating. I do not have a history of allergies or eczema.

I have not applied any medicated creams yet, only a regular moisturizer, which provides temporary relief.

Could this be a fungal infection, eczema, or an allergic reaction?

Please advise on the possible cause, whether any tests are needed, and suitable treatment or topical medication.

Thank you.

Hi,

Welcome to icliniq.com.

I understand your concern.

I am really sorry you have been dealing with this persistent itching and redness. Symptoms like these can be quite uncomfortable and distressing, especially when they worsen at night. I understand how worrying it can be when skin changes appear without an obvious trigger, and I want to reassure you that you have done the right thing by seeking timely advice.

Based on your description, itchy, red, dry, mildly scaly patches over the arms and neck that worsen with sweating and at night, the possible causes include eczema (particularly irritant dermatitis or early atopic dermatitis), allergic contact dermatitis, or, less commonly, a fungal infection.

Fungal infections usually have a more well-defined border with central clearing, whereas eczema and allergic reactions tend to cause diffuse dryness, redness, and intense itching. The fact that moisturizers provide temporary relief and there is no pain or discharge slightly favors an eczematous or inflammatory condition.

However, it is important not to make assumptions without seeing the lesions. Please also let me know if anyone at home is experiencing similar itching, or if you have recently visited someone, or had visitors, who had similar itching in the past few days. I am asking this to rule out scabies.

At this stage, a clinical examination is most important, and tests are usually not required initially unless the appearance is atypical or the condition does not respond to treatment.

To help me guide you accurately, I kindly request that you upload clear photographs of the affected areas (arms and neck), taken in good lighting, both close-up and from a slight distance. This will help differentiate between eczema, allergy, and fungal infection more confidently and allow me to advise the correct treatment.

Once I see the images, I can suggest appropriate topical medication, whether that is a mild anti-inflammatory cream, antifungal treatment, or specific skin care measures. I can also guide you on bathing habits and moisturizers that may help prevent recurrence. Until then, continue using a bland moisturizer such as petroleum jelly or calamine lotion on the affected areas. You may also take Cetirizine 10 mg at bedtime for itching for seven to ten days. Avoid scratching, keep the area cool and dry, and try to minimize sweating and friction.

I hope this has helped you.

Please feel free to reach out to me again for further queries.

Thank you.
