The medications are: • Local anaesthetics (LA): these medications numb the nerves that carry pain signals from the injured/operation site to the brain. • Opioids: also called narcotics. These medications block pain receptors to provide pain control. Opioids may be used in combination with the local anaesthetic. The medication may be given as a once only injection. When this occurs pain control should be obtained for 10-16 hours. When the nerve block begins to wear off you may experience a pins and need
