Discoid eczema (also known as nummular dermatitis) is one of several forms of eczema. It is, often, a recurring condition. When you suffer from a flare-up, the flare-up may occur for weeks or months at a time. In most cases, it is always going to appear in the same area.
Symptoms of Discoid Eczema
If you are suffering from discoid eczema, you will notice that there are small circular or oval patches on your skin. They will be red in color. While they can appear anywhere on your body, it is rare that they will appear on your face or scalp (although, some people are unlucky enough for that to happen)
When the discoid eczema flare-up first starts to occur, there will be a small group of red spots on the skin. Within a couple of days, although it can be weeks in some people, they join up and make one large, red spot.
These patches will be very swollen, almost like a blister with some fluid inside of them. They can itch a lot. In most cases, they will also be very itchy.
When the condition starts to go on for a while, then the swelling will go down. Instead, you will end up with a patch that is dry and crusty. In the center, there will be discolored skin.
In rare cases, particularly if you constantly scratch the eczema, the area may become infected. We won’t go into all the symptoms here, they are very much the same as a standard infection. This means feeling sick, chills, and you may notice a lot of fluid oozing out.
When Should You Go to the Doctor?
If you suffer from any of the symptoms that we mentioned previously, then you should make it a priority to go to your doctor. A big priority. They will be able to diagnose the condition for you and try to ensure that you are not suffering from something more serious. If you have a particularly bad flare-up, then they may also be able to provide you with medication that you can use to bring the swelling down.
What causes discoid eczema?
Nobody really knows. It is likely that it is down to dry skin. When your skin is dry, it does not really have an effective barrier against certain substances. This can cause irritation. You may notice that the condition flares up a lot if you have dry skin and you are using chemical-based skin cleaners and the like. Discoid eczema also seems to be more common in those who suffer from certain conditions such as asthma and hay fever.
Unlike Atopic eczema, Discoid dermatitis doesn’t seem to run in families.
Treatment of the Condition
Discoid eczema is treated in several different ways. Perhaps the best thing for anybody suffering from the condition is to regularly moisturize the skin. This helps to form a protective barrier which locks in the moisture and ensures that the skin does not dry out. If you have a really bad flare-up, your doctor may prescribe you with steroid creams which can reduce the swelling drastically. You will only be prescribed these ‘short term’.
