Urgent Skin Rash Inquiry: Persistent Itching and Bumps After Sleep - Dermatology

Share to:

Please respond as soon as possible!!!!


Recently, about 2 to 3 hours after going to sleep, I have been developing what looks like a rash (similar to welts from insect bites) that varies in size and some of the bumps are quite hard.
They are extremely itchy.
Initially, these appeared only on my abdominal skin, but now they have spread from my neck down to my thighs and back.
This has happened before, but only occasionally.
However, it has been ongoing for about a month now, and every day around 2 to 3 AM, the itching becomes so unbearable that I can't sleep.
I have been applying ointments, and by the next morning, the rashes are gone.
I suspect it might be insect bites, but my bed is always clean and there are rarely any bugs present.
Please, I urgently need a doctor's response on how to treat this, as I really can't endure it any longer.
Thank you!

Hello, sir: Based on your description, it is most likely allergic urticaria.
You should promptly visit a dermatologist for oral and topical medication treatment, and it will need to be taken for a period of time; it cannot be managed on your own.
Wishing you a speedy recovery.

More Info


It sounds like you are experiencing a frustrating and uncomfortable skin condition that is significantly impacting your quality of life, especially your sleep. Based on your description, the symptoms you are experiencing—itchy bumps that appear after sleeping, which seem to be spreading from your abdomen to other parts of your body—could be indicative of several potential dermatological issues.

One possibility is an allergic reaction, which can manifest as hives (urticaria). Hives are raised, itchy welts that can appear suddenly and may vary in size. They can be triggered by various factors, including allergens in your environment, food, medications, or even stress. Given that your symptoms seem to worsen at night, it may be worth considering whether there are any allergens present in your bedding or sleep environment, such as dust mites, pet dander, or laundry detergents.

Another possibility is contact dermatitis, which occurs when your skin reacts to a substance it has come into contact with. This could be something in your bedding, such as fabric softeners or detergents, or even materials in your pajamas. If you have recently changed any products you use on your skin or in your laundry routine, this could be a contributing factor.

Additionally, the fact that the bumps disappear by the morning suggests that they may not be due to a persistent skin condition but rather a reaction to something that occurs during the night. It’s also worth noting that stress and lack of sleep can exacerbate skin conditions, leading to a cycle of itching and discomfort.

Given the persistence and severity of your symptoms, it is crucial to seek medical attention from a dermatologist. They can perform a thorough examination and may recommend patch testing to identify any potential allergens. In the meantime, here are some general recommendations that may help alleviate your symptoms:
1. Keep a Diary: Track your symptoms, including when they occur, their severity, and any potential triggers (such as foods, products, or activities). This information can be helpful for your healthcare provider.

2. Change Bedding: Consider washing your bedding in hot water and using hypoallergenic detergents. You might also want to encase your pillows and mattress in dust mite-proof covers.

3. Moisturize: Apply a fragrance-free moisturizer to your skin regularly to help maintain hydration and protect the skin barrier.

4. Avoid Scratching: While it may be tempting to scratch the itchy areas, doing so can worsen the irritation and lead to secondary infections. Instead, try using cold compresses to soothe the itch.

5. Over-the-Counter Remedies: Antihistamines may help reduce itching and are available over the counter. However, consult with a healthcare provider before starting any new medication.

6. Consult a Dermatologist: Since your symptoms have persisted for a month and are affecting your sleep, it’s essential to see a dermatologist for a proper diagnosis and treatment plan. They may prescribe topical corticosteroids or other medications to help manage your symptoms.

In summary, while there are several potential causes for your symptoms, a thorough evaluation by a healthcare professional is necessary to determine the exact cause and appropriate treatment. Don't hesitate to seek help, as managing skin conditions effectively can greatly improve your quality of life.
