What Causes Itchy Bumps On Skin?

Itchy tiny bumps on the skin can become red and irritated and cause rashes and infection on the skin if continuously scratched. If you are experiencing bumpy rashes on your skin, finding a treatment for it is essential. But before looking for a solution it is important to understand its causes. 

There are several factors that may be causing your skin to become itchy and bumpy, we have listed some of the most common causes below.

1. Eczema

Commonly known as Atopic Dermatitis, eczema is a chronic skin condition that causes itchy, irritated, inflamed dry skin. It can sometimes also cause small itchy bumps on the skin. It can also cause rashes on the skin that may vary in color. For people with lighter skin tones rashes are of red color and in darker skin tones they are purple or brownish.

Eczema is believed to be caused by a combination of factors such as genetics, stress, and allergens. Everyone can experience eczema, no matter what age but it is more common in children under the age of 5, then it is termed as baby eczema. 

In some cases, eczema may disappear but most of the time, it persists and reoccurs as eczema flare-ups throughout life. Even though there is no permanent cure for eczema, itching, dryness, and inflammation associated with it can be easily managed by following a proper skincare routine that includes the use of Eczema shampoo and body wash to keep the affected area clean and an eczema cream to keep the skin moisturized. 

2. Contact Dermatitis

Contact dermatitis as the name suggests appears when the skin comes in contact with a harmful substance. In simpler words, the itchy red bumps caused by contact dermatitis are a reaction of the skin towards those allergens. 

Contact dermatitis comes in two forms: allergic contact dermatitis (ACD) and irritant contact dermatitis (ICD). With allergic contact dermatitis, the skin comes in contact with something you become allergic to such as nickel, metals, or poison ivy. The body then becomes sensitized, and when re-exposed to that same allergen the immune system releases a certain type of T-cells that causes the itchy bumps on the skin to appear–often days later.

 

With irritant contact dermatitis the skin becomes irritated due to certain irritants upon contact, these can be the chemicals used in beauty products, detergents, and soaps. 

Contact dermatitis can be managed by staying away from the allergens and irritants. But if you are unsure about what is causing these itchy bumps contact your healthcare provider.

3. Hives

Hives cause raised itchy patches on the skin. Hives are caused by an allergic reaction. When you consume or come in contact with something you are allergic to. Itchy, irritating bumps appear on your skin. Some of the common triggers that may cause hives are peanuts, seafood, latex, pollen, and medications. 

Hives, also known as urticaria, have two common types. Acute urticaria is when the hives don’t stay for a long period–usually less than 6 weeks. And chronic urticaria is when the hives last for more than 6 weeks. Antihistamines are usually prescribed by the doctors to get rid of hives.

4. Scabies

Itchy skin bumps are one of the most common symptoms of scabies. Scabies is caused by itch mites also known as Sarcoptes scabiei, they dig their way through the topmost layer of the skin and lay eggs. These then cause intense itching and scratching these tiny bumps can make the condition worse and cause infection.

Scabies usually appear on the chest, wrists, groin area, armpits, and between toes and fingers. The worst thing about it is that it is contagious and can spread from one person to another. So, it is crucial to treat scabies as soon as possible. According to Mayo Clinic, it can easily be treated with the help of medicated skin creams and that kill the mites. 

5. Chickenpox

Likely you have heard the name chickenpox and may have experienced it. Almost everyone in this world used to get chickenpox once in their lifetime–but with vaccines, it is much less common.  Most people experience it in their childhood while others have to bear it when they grow old.

Itchy raised bumps are one of the most prominent features of chickenpox. These bumps and blisters are usually filled with clear liquid. It is believed to be caused by the varicella-zoster virus. It usually lasts for about 10 days and is accompanied by fever, body pain, and headaches. 

The best way to prevent chickenpox is by getting vaccinated. In most cases, the vaccine may prevent chickenpox from appearing but if it still does the symptoms associated with it are milder.

6. Flea Bites

Flea bites are caused by tiny bugs known as vectors, that thrive on the blood of animals and humans. These fleas when biting your skin discharge saliva into your bloodstream. The body’s immune system considers this saliva as an allergen and causes skin reactions. These can be transmitted from animals to humans easily. These bites can cause itchy discolored bumps to appear on the skin. 

These bumps can be very itchy, but scratching them can make the condition worse. It can also lead to different skin infections. Flea bites can be easily treated with over-the-counter anti-itch creams and antihistamines.
