After the skin is heated, it induces the release of histamine, causing the onset of urticaria. Patients with urticaria are particularly prone to urticaria when the skin is heated. It will be manifested as redness and itching of the skin, but this symptom will subside faster. When the skin calms down, after a while, the symptoms will be significantly relieved. If the symptoms appear for a short time, they will be relieved quickly and do not need treatment.
