The itching symptoms of eczema at night are more serious, which may be because the sympathetic nerve function of the patient is weakened at night, the secretion of adrenaline is reduced, and the excitability of parasympathetic nerve is increased, causing the release of some neurotransmitters related to itching, thus aggravating the itching symptoms. In the daytime, patients do not pay too much attention to eczema when working, studying or doing other things, but at night, patients may pay more attention to eczema, so they may feel that the itching symptoms are aggravated. To alleviate the itching symptoms of eczema at night, you can apply anti itching ointment such as glucocorticoid preparation under the guidance of a doctor. Eczema can lead to skin rashes with needle tip size and flaky aggregation, and there will be obvious exudate at the rash. When there is itching, you should avoid scratching, otherwise the skin may appear ulceration, secondary infection, and even leave scars.
