3 of the Most Common Rashes

3 of the Most Common Rashes

Skin rashes come in many forms, from red, itchy, and localized to stinging and spread across large areas of your body. If you have a rash, chances are you want to know why and whether you should seek medical help.  

At Urgent Care of Ada, our medical providers help men, women, and children in Ada, Oklahoma, struggling with rashes by providing expert diagnosis and treatment. We’ve gathered information on three of the most common rashes, so you can better understand when to seek help.  

1. Contact dermatitis

One of the most common types of rashes we treat here at Urgent Care of Ada is contact dermatitis. This type of rash results because of an allergic reaction between your skin and an irritant or allergen.  

Irritant contact dermatitis is more common and happens when your skin responds to substances that irritate the skin cells, like detergents, soaps, bleach, metals, makeup, and more. Even washing your hands too often or wearing certain materials can trigger this type of contact dermatitis, which can cause:

Allergic contact dermatitis, on the other hand, happens when you have an allergic reaction to something you touch. In this case, you typically get the rash a day or so after you’re exposed to the allergen, though it may happen faster. 

Common types of allergic contact dermatitis include poison ivy, reactions to certain chemicals, like fragrances, nickel, preservatives, and certain medications. This type of rash generally causes:

Most of the time, contact dermatitis goes away on its own once the irritant or allergen loses contact with your skin. If the rash is close to your eyes, mouth, or covers a very large area of your body, you should come to Urgent Care of Ada for medical attention. 

2. Atopic dermatitis (eczema)

The most common type of eczema, called atopic dermatitis, impacts millions of adults and children across the US. If you suffer from it, you may have rashes that come and go for years. 

Though researchers are still investigating the exact causes of this type of eczema, scientists believe it’s triggered when your immune system becomes overactive and triggers inflammation in the skin. This inflammation causes the skin to become irritated, dry, and change in color. 

Atopic dermatitis often occurs in people who have seasonal allergies or hay fever and asthma. Some signs you may have atopic dermatitis include:

Be sure to schedule an exam at Urgent Care of Ada if your eczema becomes so itchy or uncomfortable you can’t continue with your normal activities, your rash appears infected, or your rash doesn’t clear up on its own. 

3. Pityriasis rosea (herald rash or Christmas tree rash)

Another common skin rash is called pityriasis rosea. This common skin condition usually clears up on its own, but since it shares symptoms with other types of rashes, it’s important to have a provider at Urgent Care of Ada diagnose your rash to make sure it isn’t cause for concern. 

Pityriasis rosea isn’t contagious, but doctors believe it’s usually triggered by exposure to a virus and accompanied by feeling unwell (e.g., sore throat, headache, fever) for one to two days. You may also notice swollen lymph nodes just before the rash starts.

The rash usually starts on your back or torso with a single “herald” patch that’s about 2-10cm and oval in shape. It might be rough to the touch or slightly raised. After a week or so, other smaller rashes form, frequently resembling the shape of a Christmas tree. These smaller patches are usually scaly and might become itchy when you get hot or exercise. 

Although this type of rash usually clears up on its own, your Urgent Care of Ada provider can prescribe medications to help with the itching and swelling pityriasis rosea may cause. 

NOTE: If you’re pregnant and develop signs of pityriasis rosea, seek medical attention immediately as studies indicate a higher risk of birth complications, miscarriage, and neonatal distress.  

If you’re struggling with a rash, let the team at Urgent Care of Ada help. Contact our Ada, Oklahoma, office for more information about scheduling an appointment, or walk in to our urgent care clinic for same-day care.
