ABSTRACT
Analgesia means the relief of pain. It may be general, by the use of drugs such as Aspirin and Paracetamol which, when taken, will relieve pain from different causes in various parts of the body, or may be localised, most usually by injection or spraying of a local analgesic agent. Although often termed local anaesthesia, it should more correctly be termed local analgesia since it relieves pain rather than induces sleep.
