===Chronic pain===

[[Chronic pain]] is a complex and often serious condition that requires diagnosis and treatment by an expert in pain medicine. LAs can be applied repeatedly or continuously for prolonged periods to relieve chronic pain, usually in combination with medication such as [[opioid]]s, [[NSAID]]s, and [[anticonvulsant]]s. Though it can be easily performed, repeated local anesthetic blocks in chronic pain conditions are not recommended as there is no evidence of long-term benefits.<ref>{{cite journal | vauthors =  | title = Current world literature.
