Yesterday I went out for a swim, but today I found that I had some red spots on my back and thigh. It's useless to wipe them with ointment. Later I learned that it's very similar to the symptoms of psoriasis. Now let's understand what the symptoms of psoriasis are.

What is psoriasis symptom

First, it starts with inflammatory red papules, about the size of millet to mung bean, and then gradually expands or fuses into brownish red plaques with clear boundary, inflammatory red halo around, obvious basal infiltration, and multi-layer dry grayish white or silvery white scales on the surface. Gently scrape off the surface scales, gradually exposing a layer of light red shiny translucent film, called film phenomenon. Then scrape off the film, there will be small bleeding points, known as punctate bleeding phenomenon.

Second, the most common type is common in clinic. The skin lesions are various in shape, such as drops, coins, maps, rings or loops, and oyster shells. The three clinical features of typical skin lesions are silvery white scale, membrane phenomenon and cribriform hemorrhage. The rash usually occurs on the scalp and limbs.
