First of all, urticaria is actually very different from eczema. Urticaria is generally like an allergic reaction, which produces itching or lumps that come and go.
If there is a lump or itching on the skin, but it is ignored and disappears in almost two days, then this is probably urticaria.
If the symptoms of these lumps or itching have not been alleviated or subsided after two days, it is generally not urticaria. If urticaria is ruled out, we need to see if it is eczema according to some symptoms of eczema.
Generally eczema has many characteristics in appearance, which can be manifested as macula, that is, erythema and papules that look one after another, that is, small bumps that swell up.
There may also be blisters, as can be seen from the name, that is, there is shiny liquid inside. In addition, there is a herpes mound, that is, there is a small blister on the swollen papule.
From my introduction above, we can also see that eczema has many external characteristics. Of course, in addition to these appearance characteristics, eczema can also be judged, and some small details are also possible.
Eczema is generally symmetrically distributed, so if only one side has symptoms, it is probably not eczema. The above are some of my views, hoping to help everyone.
