As we have talked about before, the cause of eczema is very complex and is caused by the interaction of many factors, including, of course, food factors, some people eat fish, shrimp, beef and mutton and irritating food will aggravate eczema, then these people should pay attention to try not to eat these foods that can aggravate the disease. What should we pay attention to if we have eczema? The first thing to do is to find out what causes eczema or aggravates it. For example, some people are exposed to dust, eczema will worsen; some people wear chemical fiber clothing, the rash worsens; some people have indigestion, eczema will also worsen, etc.. If we can find the cause, we find ways to avoid it, eczema will be easy to cure. But sometimes the cause is very difficult to find, which needs to be slowly figured out in daily life. The second thing to note when you get eczema is that you should never scratch hard or use hot water to wash. If the itch is severe, you can take some antihistamines, such as paracetamol, under the guidance of your doctor. If the rash is small, you can apply some hormonal creams. If it does not work, then you should go to the hospital to see a doctor.
