What is a Skin Rash?

A rash is a noticeable change in the texture or color of your skin. Your skin may become scaly, bumpy, itchy, or otherwise irritated. Rash is not a specific diagnosis. Instead it refers to any sort of inflammation and/or discoloration that distorts the skin’s normal appearance. Common rashes include eczema, poison ivy, hives, and athlete’s foot.

 

What causes a Skin Rash?

Cause of rash on skin may be fungal, bacterial, parasitic, or viral. Over-the-counter products may be helpful treatments for different types of skin rashes. Rashes lasting more than a few days that are unexplained should be evaluated by a doctor. Each rash has a different cause, but symptoms are nearly always similar.

Common Symptoms of Skin Rashes:-
  • Blister formation
  • Scaling
  • Skin ulceration
  • Skin discoloration
  • Itching
  • Bumps on skin

What are different types of Rashes?

There are many different causes for rashes. Here’s a list of most common with pictures.

1) Flea Bites

Fleas are tiny, irritating insects. Their bites are itchy and sometimes painful, and getting rid of them is hard. Sometimes professional pest control treatment may be required.

Fleas reproduce quickly, especially if you have pets in the household. But even if you don’t have pets, your yard can potentially play host to fleas, and you may end up with a bunch of mysterious bites. Symptoms include:

  • Usually located in clusters on the lower legs and feet.
  • Itchy, red bump surrounded by a red halo.
  • Symptoms begin immediately after being bitten.

2) Fifth Disease

Fifth disease is viral illness that most kids recover from quickly and without complications. Also called erythema infectiosum, it’s caused by parvovirus B19. It’s especially common in kids ages 5 to 15. In older kids and adults, fifth disease can cause joint swelling and pain that can last from weeks to months and, very rarely, years.

Fifth disease causes a distinctive red rash on the face that makes a child appear to have a “slapped cheek.” A few days later, the rash spreads down to the trunk, arms, and legs. It usually lasts 1 to 3 weeks.

  • Headache, fatigue, low fever, sore throat, runny nose, diarrhea, and nausea.
  • Children are more likely than adults to experience a rash.
  • Round, bright red rash on the cheeks.
  • Lacy-patterned rash on the arms, legs, and upper body that might be more visible after a hot shower or bath.

3) Rosacea

Although the exact cause of rosacea is unknown, various theories about the disorder’s origin have evolved over the years. Facial blood vessels may dilate too easily, and the increased blood near the skin surface makes the skin appear red and flushed. Various lifestyle and environmental factors can increase this redness response. Acne-like bumps may appear, often in the redder area of the central face. This may be due to factors related to blood flow, skin bacteria, microscopic skin mites (Demodex), irritation of follicles, sun damage of the connective tissue under the skin, an abnormal immune or inflammatory response, or psychological factors.

  • Chronic skin disease that goes through cycles of fading and relapse.
  • Relapses may be triggered by spicy foods, alcoholic beverages, sunlight, stress, and the intestinal bacteria Helicobacter pylori.
  • The four sub types of rosacea encompass a wide variety of symptoms.
  • Common symptoms include facial flushing, raised, red bumps, facial redness, skin dryness, and skin sensitivity.

4) Impetigo

It’s an infection of the skin caused by bacteria. Impetigo is commonly found on the face, often around the nose and mouth, but it can show up anywhere the skin has been broken. If you have a cut or scrape or if you scratch your skin because of a bug bite, eczema, or poison ivy, germs may find a way to get inside.

  • Common in babies and children.
  • Often located in the area around the mouth, chin, and nose.
  • Irritating rash and fluid-filled blisters that pop easily and form a honey-colored crust.

5) Ringworm

It is a common fungal skin infection otherwise known as tinea. Most commonly affects the skin on the body (tinea corporis), the scalp (tinea capitis), the feet (tinea pedis, or athlete’s foot), or the groin (tinea cruris, or jock itch).

  • Circular-shaped scaly rashes with raised border.
  • Skin in the middle of the ring appears clear and healthy, and the edges of the ring may spread outward.
  • Itchy on and around.
