What is Eczema?
Eczema is an itchy skin rash, usually develops in babies and young children, and may continue to flare up in adults. Eczema can range from mild to extreme levels of itch.

Some other areas susceptible to eczema are wrists, forearms, and chest.
What is the root cause of Eczema?
See the below types of Eczema for slight differences. For this question we will focus on the most common form of Eczema, Atopic Dermatitis. Research suggests that some people are genetically predisposed to Eczema. The body produces a protein called Filaggrin which helps protect the outer most layer of the skin. There is a link between people who develop Eczema and a mutation of the gene responsible for producing Filaggrin. Its believed that eczema is caused by a combination of factors. Eczema tends to flare up when when these people have a weaken immune system and are exposed to some form of allergy.
It should be noted the exact cause of eczema is unknown, however the above appears common, and research is ongoing.

What are the different types of Eczema?
There are seven different types of eczema;
Atopic Dermatitis – the most common form of Eczema
Atopic eczema is the most common form of eczema. Often associated with hay fever and asthma.
Contact Dermatitis is triggered as a reaction to something that you touch, either a chemical or substance. Common chemicals or substances causing Contact Dermatitis include; detergents, bleach, jewelry, latex, paint, plants, makeup, soaps and perfumes, and solvents.
Dyshidrotic Eczema is defined by fluid-filled blisters on your fingers, toes, palms, and soles of your feet.
Hand Eczema is defined as Eczema that only forms on the hands. This is most common for people that expose their hands to chemicals and solvents for their work. Hairdressers, laundry works, panel beaters, and mechanics are common sufferers of Hand Eczema.
Neurodermatitis is similar to Atopic Dermatitis although the trigger is often thought to be stress related. Neurodermatitis may not need a specific allergy to trigger. It is thought to flare up when a person genetically predisposed to Eczema, is highly stressed.
Nummular is Latin for “coin”. Nummular Eczema appears as small coin shaped and sized inflamed and itchy patches of skin. Nummular Eczema may be triggered from an insect bite or other allergic reaction. It is more common if you have previously experienced other forms of Eczema, such as Atopic Eczema.
Stasis Dermatitis is associated with varicose veins. Fluid leaks out of the damaged varicose veins and dry itchy skin develops over the top of the varicose veins. Legs may become swollen, and walking for long periods or long periods of inactivity may contribute.
What other symptoms are associated with eczema?
Eczema sometimes precedes Asthma and hay fever. More than half of young children with atopic dermatitis develop asthma and hay fever by age 13.
Eczema can lead to increasingly itchy skin. Scratching the Eczema effected skin further inflames the skin making it itchier, with the patient then wanting to scratch more.
Skin infections are often associated with Eczema. Scratching the skin causes open sores and cracks increasing the risk of bacterial skin infection.
Constant itching often causes disrupted sleep. People often report they feel most itchy when relaxing. The need to itch can wake people from deep sleep cause a loss of quality sleep.
How can I prevent Eczema from reoccurring?
To prevent Eczema from reoccurring, you must first understand the type and the likely cause.
If it is caused by a particular fabric such as wool, stop wearing wool.
Perhaps it is associated with your working environment, consider wearing gloves, and keeping hands dry.
Moisturize your skin regularly, 3 to 4 times per day at regular intervals.
Remove all chemicals, detergents including dish washing and laundry, bleaches, solvents perfumes, deodorants, and any scented soaps. Try antibacterial or unscented natural type soaps.
After bathing, pat dry yourself. Vigorous drying can inflame the skin causing you to itch.
Consume non inflamatry foods. Common food allergies apply here, avoid peanuts, milk, soy, wheat, fish, and eggs.
Once the Eczema symptoms disappear reintroduce the above one at a time slowly to help determine your personal Eczema trigger.
Does Eczema go away on its own?
No. Eczema will continue if the cause is not found or the symptom is not treated.
Why does Eczema hurt?
Eczema is a skin reaction where the skin becomes mildly inflamed. The level of skin inflammation caused by Eczema itself does not usually cause much pain. Further problems such as skin infection from excessive itchy and damaging the surface of the skin are usually the source of pain. Prevention is always better than the cure, seeking treatment from the best Dermatologist early, before the skin is damaged, is the best advice to reduce pain.
