What are the symptoms of nail psoriasis?

Symptoms of nail psoriasis also include that the rash of psoriasis can spread to any part of the whole body skin, including the palms and soles of the feet, but it is generally rare, and it can coexist with rashes in other parts of the body, or it can appear alone on the palms and soles of the feet. It is a keratinized plaque with obvious gap. Its center is thick and its gap is thin. The plaque can be dotted with white scales or depressions. When there is no dandruff, palms and soles are easy to be mixed with calluses or keratinized skin diseases. Repeated conflicts or the influence of chemicals will make the injury hypertrophy and expand, leading to chapped palms and soles.
