Ant stings occur when certain species of ants, such as fire ants, inject venom through their stingers. This venom can cause pain, redness, and swelling at the sting site. The severity of the reaction varies depending on the individual's sensitivity and the type of ant involved. Most ant stings are not life-threatening, but some people may experience allergic reactions, which can lead to more serious symptoms. It's important to clean the sting area and apply cold compresses to reduce swelling. In case of severe reactions, seeking medical attention is recommended.
