Condition GuidancePsoriasisCommon symptoms of psoriasis include thick, raised inflammatory plaques and silvery-white scales on the scalp, elbows, knees, torso, palms, and soles. The skin may feel itchy, burning, stinging, or tight, and may crack dryly and bleed. Depending on the type, it may appear as small droplet-shaped skin changes, smooth rashes in skin folds, pustular skin changes on the hands and feet, or severe redness and scaling across the entire body. This may be accompanied by small pits, thickening, or crumbling of the fingernails and toenails, as well as joint pain, swelling, morning stiffness, and heel pain. If the entire body suddenly turns red, or if pustular skin changes occur with fever and a worsening general condition, seek prompt medical evaluation.Condition GuidanceChronic eczemaChronic eczema is characterized by dry, rough skin; recurring redness and itching; scaling and cracking; and skin that has become thick and hardened from prolonged scratching. Depending on skin tone, redness may be less visible or may appear darker, such as brown, gray, or purple. In the hands or skin folds, cracking may occur after contact with water or friction, leading to pain or bleeding. If the condition worsens, clear discharge and crusting may occur. Yellow crusts, pus, heat, a rapid increase in pain, and fever require a check for possible infection. Nighttime itching, loss of sleep, and discomfort when using hands, washing, or dressing are also significant symptom burdens.Condition GuidancePityriasis RoseaPityriasis rosea typically begins with a large, oval 'herald patch' with scales on the edges appearing on the chest, abdomen, or back, followed by smaller oval patches spreading to the torso and limbs. On the back, these may be arranged like a Christmas tree along the skin folds. Depending on skin tone, they may appear pink, red, purple, gray, or brown, and itching may be absent or severe. If there are new rashes during pregnancy, painful blisters, mucosal skin changes, fever, difficulty breathing, or rapid worsening, you must seek prompt medical evaluation as other causes must be checked first.Medical Evaluation GuidePrepare for your visit with skin photos, symptoms, and medications usedRather than a single photo, please prepare a chronological record of the date the symptoms first appeared, the timing of when they disappear and reappear, itching and pain, and the medications used and your reactions to them. It is helpful for the medical evaluation to take photos of the same area from the same distance during both normal states and when symptoms are most severe.
