Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for throat is pharynx.
Treatment depends on the cause. Sucking on lozenges, drinking lots of liquids and gargling may ease the pain. Over-the-counter pain relievers can also help, but children should not take aspirin.
