Eczema can occur all over the body, but is most common on the hands, insides of the elbows, or backs of the knees.
At least one in five children in the UK have eczema, and they may find it on their face and scalp.
Eczema is more severe in some than others, and can affect the whole body with constant itching.
The scratching can disturb your sleep, cause nose bleeds, and lead to infections.
If the skin gets infected, you may notice fluid oozing from your skin, swelling, and hot and cold flushes.
