A local anesthetic is a type of medication that numbs a specific area of the body to prevent pain during medical procedures or surgery. It is applied directly to the skin, injected into the tissue, or given near nerves to block the sensation of pain in that particular area. Local anesthetics work by temporarily blocking the transmission of nerve signals, preventing them from reaching the brain. This allows healthcare providers to perform procedures without causing discomfort to the patient in the targeted area.
