What is the recommended first step for treating an insect sting caused by a bee?

Applying an ice pack to the affected area is the recommended first step for treating an insect sting caused by a bee. This action helps reduce swelling and minimizes pain by numbing the area. The cold temperature of the ice pack constricts blood vessels, which can alleviate the inflammatory response that follows the sting.

In addition to providing immediate pain relief, the ice pack can help prevent the venom from spreading by slowing down blood flow to the area. It's important to wrap the ice pack in a cloth to avoid direct contact with the skin, which can lead to frostbite.

While other methods, such as applying heat, using topical ointments, or calling emergency services, may be relevant in specific situations, they are not the first steps in immediate care following a bee sting. Heat is generally not advised, as it can exacerbate swelling and pain. Topical ointments may be used later to soothe itching or irritation, and calling for emergency services would only be necessary in severe cases, such as an allergic reaction.
