The symptoms of psoriasis on the hands are varied and complex. It usually occurs on the scalp, extensor surfaces of the limbs and the back. It is more common in men than in women. Psoriasis tends to recur or worsen in the spring and winter months, while it tends to remit in the summer and fall. Although psoriasis does not directly affect life, it has a direct impact on physical health and mental and physical well-being. Psoriasis begins as a pinhead to lentil-sized inflammatory flat papule that gradually grows into a coin or larger pale red infiltrated patch with clear boundaries and is covered with multiple layers of silvery white scales. Gently scrape away the surface scales, then reveal a layer of light red shiny translucent film, called film phenomenon. If the film is scraped away again, small bleeding spots appear, called punctate bleeding phenomenon. The onset of psoriasis on the hands is relatively quick. In the process of treating psoriasis, a rash may appear on the patient’s hands, or it may extend from scalp damage. Sometimes head and hand damage can also occur alone. The lesions are mostly seen on the palms, backs of hands, and finger joints, and are mostly in the form of dotted papules or erythematous spots the size of nail caps, or sometimes they can appear as seborrheic dermatitis-like or erythematous vicious sore-like lesions often accompanied by itching. If the skin itches, the patient must not scratch too hard. During the development of psoriasis, the patient’s lesion pattern can take many forms. In the acute phase, the lesions are mostly spotty, bright red, and itchy. The actual fact is that the actual person has a lot of time to get a lot of money. The lesions in the regressive phase are often annular or semi-annular in shape. A few rashes have thicker scales, sometimes piling up like shell oysters. The experts reminded: psoriasis is very harmful, so suffering from psoriasis must be timely to treatment, if there are any questions, you can consult with experts.
