Psoriasis can appear anywhere on the uman body. Depending on
how bad the area is, and
how built of the skin cells are, psoriasis can be non-painful but usually it has some sort of discomfort associated with it. If it is on the genitals, it can be painless and usually it can be easily diagnosed because genital psoriaisis tends to shed the built up skin quickly. If you do not have built up patchy skin on the genitals than more than likely it is eczema. However, psoriasis tends to itch.
