Hives, a type of skin disorder, typically present as raised wheals of varying sizes on the skin, accompanied by itching and sometimes angioedema. In most cases, hives disappear completely within minutes to hours without leaving any trace. However, during an outbreak, scratching due to intense itching may damage the skin, leading to breaks in the skin surface and possible secondary infection, which could result in residual marks after the hives resolve. Additionally, topical application of corticosteroid medications for treating hives may also cause skin discoloration or other marks.

When experiencing hives, it is recommended to maintain a light diet and avoid raw, cold, or irritating foods. Avoid scratching the affected areas. If itching is severe, antihistamines such as loratadine or cetirizine hydrochloride may be taken under medical supervision to relieve symptoms.
