Could your itchy rash be a symptom of eczema? It’s possible. Eczema, also called dermatitis, is a term that covers many types of skin problems.
The way to know for sure whether you have it or not is to see a doctor. But there are some common warning signs you can watch for.
People usually have their first eczema symptoms when they’re babies. But children and adults can have the condition. No two people have exactly the same symptoms.
In general, the disease often appears as skin patches that can be:
- Very itchy
Rashes tend to come and go. With time, they can get crusty and scaly. Some types of eczema can also blister, leak fluid, crack, or peel. An infection or too much scratching can make your symptoms worse. It can even make your skin thick and leathery.
You can have eczema anywhere on your body, but it often shows up on the:
- Insides of your elbows
- Backs of your knees
- Face, often on the cheeks
- Behind the ears
- Hands and feet
Sometimes, you may have other skin changes along with eczema, such as small raised bumps or hives. Or, you might have an extra fold of skin under your eyes.
Other Problems From Eczema
When you scratch too much, your skin might break open a little. This allows bacteria or viruses to get inside and can lead to an infection.
Sometimes, the medications you take to control eczema can also cause other health problems if you take them for a long time.
Although eczema symptoms tend to die down as babies get older, people who had the condition as infants are at higher risk for other skin problems throughout life, like sensitive skin, infections, or eyelid dermatitis.
How It's Diagnosed
The best way to diagnose eczema is for a doctor to get your entire medical and family histories. She may ask about:
- If you have asthma or allergic reactions, such as to pollen, pets, or foods
- Substances that tend to irritate your skin, like soaps or cosmetics
- Any recent extra stress
- Where and when your symptoms started
- Any treatment you’ve had for other skin conditions
The doctor can sometimes tell by looking at a rash whether or not it’s eczema. But it may take more than one visit to rule out other problems. The doctor might also refer you to a specialist, such as a dermatologist or allergist.
There's no test for eczema, but allergy testing can help pinpoint any allergic triggers. Other common triggers include irritants, heat, or stress.
What to Ask Your Doctor
When you talk with your doctor, get as much information about your condition as you can. Here are some questions to get you started:
- What's the cause of my eczema?
- What's the best way to treat it?
- Do I need a prescription?
- Is there anything new that might work better than what I've tried in the past?
- Can I prevent a new outbreak of eczema?
- When should I call you about my symptoms?
