Why do I have itchy red rashes all over my body?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 28-year-old woman who has been experiencing troubling skin issues recently. Itchy, red rashes persistently appear all over my body, significantly impacting my daily routine. I have come across conditions such as atopic dermatitis, and I am curious if this might be the cause of my skin problems. Could you provide more information about atopic dermatitis and its connection to allergies? Additionally, I would appreciate any suggestions for home remedies or treatments that could help alleviate the irritation on my skin in the interim.

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I can understand your concern.

Atopic dermatitis is a chronic allergic skin condition commonly characterized by dry skin and itching, and it may also manifest as asthma. It typically manifests during infancy and tends to improve with age. Diagnosis requires specific criteria and a physical examination of the skin. Associated asthma may also be present.

If your symptoms have recently appeared, it is less likely to be atopic dermatitis. It could be urticaria, where hives occur, or sometimes there are no visible hives, known as silent urticaria. You need to identify the triggering agent in your diet, or medication, or it may also be internal. Take good care of your skin, avoid harsh soaps, and use generous amounts of emollients.

I hope this information will help you.

Thank you.

How it works

Itchy red rashes that show up suddenly across the body in adulthood are more often hives (urticaria) than eczema (atopic dermatitis), even when there are no visible welts. The five steps below walk through how a clinician tells them apart, what triggers to look for, and what you can do tonight while you wait for a visit.

Why this matters

Eczema (atopic dermatitis) usually starts in childhood. When widespread itchy rashes show up for the first time in adulthood, the doctor's note that this might actually be hives (urticaria), sometimes without visible welts, is worth taking seriously. The next step is not a diagnosis at home. It is a trigger journal for your visit.
