Red Bumps on Skin: Causes and Treatments

Acne on the skin?

Hello, I have recently developed skin lesions that resemble pimples.
They are red, about the size of a red bean, and the surface of the wounds is depressed.
When squeezed, they only release fluid, unlike typical pimples that have comedones.
Additionally, they seem to worsen if I don't get enough sleep.
What could this condition be? Thank you.

More Info

Red bumps on the skin can be concerning, especially when they resemble acne but have different characteristics. Based on your description, it sounds like you may be experiencing a condition known as folliculitis, which is the inflammation of hair follicles. This can present as small red bumps that may be filled with fluid, and they can become more pronounced with irritation or pressure, such as when lying down.
There are several potential causes for these red bumps:
1. Folliculitis: This is often caused by bacterial or fungal infections, irritation from shaving, or blockage of hair follicles. It can appear as red, inflamed bumps that may contain pus or fluid.

2. Allergic Reactions: Sometimes, skin reactions can occur due to contact dermatitis, which is an allergic reaction to products like soaps, lotions, or even fabrics. This can lead to red, itchy bumps.

3. Acneiform Eruptions: While you mentioned that these bumps are not like typical acne, there are various forms of acne that can present differently, including cystic acne, which can cause painful, fluid-filled bumps.

4. Hives (Urticaria): These are raised, itchy welts that can appear suddenly and may be triggered by allergens, stress, or other factors. They can vary in size and may come and go.

5. Other Skin Conditions: Conditions like eczema, psoriasis, or even viral infections can also cause red bumps on the skin.

Given that you mentioned the bumps worsen with sleep, this could indicate that pressure or friction is exacerbating the condition. It’s important to avoid squeezing or picking at the bumps, as this can lead to further irritation or infection.

Treatment Options
1. Topical Treatments: Over-the-counter topical antibiotics (like Neosporin) can help if the bumps are due to bacterial folliculitis. If it’s an allergic reaction, a topical corticosteroid cream may reduce inflammation and itching.

2. Antihistamines: If you suspect an allergic reaction, taking an oral antihistamine like Benadryl can help alleviate itching and swelling.

3. Good Hygiene: Keeping the affected area clean and dry is crucial. Use a gentle cleanser and avoid harsh scrubs that can irritate the skin further.

4. Avoid Irritants: Identify and avoid any products that may be causing irritation. This includes soaps, lotions, or even laundry detergents.

5. Consult a Dermatologist: If the condition persists or worsens, it’s advisable to see a dermatologist. They can provide a proper diagnosis and may prescribe stronger topical or oral medications, depending on the underlying cause.

When to Seek Medical Attention
If you experience any of the following, seek medical attention promptly:
- The bumps are spreading or worsening.

- You develop a fever or systemic symptoms.

- The bumps become painful or show signs of infection (increased redness, warmth, or pus).

- You have a history of skin conditions that complicate the diagnosis.

In conclusion, while red bumps on the skin can arise from various causes, understanding the characteristics and potential triggers is essential for effective treatment. Maintaining good skin hygiene, avoiding irritants, and consulting with a healthcare professional when necessary will help manage the condition effectively.
