What are hives?

Hives are a  cutaneous pathology usually banal and of short duration, although it can create unrest in those who suffer from it. It usually occurs with the appearance of “welts” or weals, which are small elevations or bumps in the skin more or less reddish, that itch a lot, but usually disappear in less than 24 hours without leaving an injury, although they can appear and disappear several times over a certain period of days or weeks.
