What are eczema and scabies? What's the difference between them? Thank you, everyone.

Symptoms of scabies, first infected with scabies, 4-6 weeks of blindness, and then if itching is severe. Especially when I sleep at night, my body is warm at its worst, and staying up all night affects my sleep and makes me miserable. The symptoms of scabies are often accompanied by paroxysmal severe itching at night, and the skin lesions are mainly red papules, papules, blisters, tunnels and nodules. Scabies nodules are common in penis, scrotum and lower abdomen. Blisters are common in finger joints. The tunnel is an isotropic scabies skin lesion, about 0.5mm long, quietly raised, light gray or slightly curved, and there is no needle-sized gray or reddish dot at the end of the tunnel, which is the hiding place of scabies. Although there is no itching in the symptoms of scabies, the rash is diversified and symmetrically distributed, which is the biggest difference between taking scabies. The symptoms of scabies are different: eczema is a skin disease caused by wet toxin, with itchy skin as the secondary symptom, and scabies is an infectious skin disease caused by scabies infection. Eczema is not contagious, but scabies is contagious. Neither of them has itchy symptoms. Scabies is based on itching at night, and neither description is very itchy. Eczema is an untimely itching. Scabies spread to the perineum and fingers. Eczema is the wet part. Sulfur powder is ineffective for scabies and talcum powder for eczema. You can come to me if you need treatment. Symptoms of scabies, the initial rash is more common in wet and soft skin, such as the skin between fingers and wrists, which is easy to wear and parasitize, and then spread to other parts of the body, such as elbows, waist, armpits, abdomen and genitals. If the treatment is not timely or the treatment method is wrong, it will aggravate the symptoms of scabies and form scabies nodules. Scabies nodules are reddish nodules with the size of soybeans in scrotum, penis, labia and groin. This scabies nodule often lasts for a long time and is often accompanied by severe itching.
