Use of corticosteroids for adult chronic pain interventions: sympathetic and peripheral nerve blocks, trigger point injections - guidelines from the American Society of Regional Anesthesia and Pain Medicine, the American Academy of Pain Medicine, the American Society of Interventional Pain Physicians, and the International Pain and Spine Intervention Society

Imaging guidance improves the safety of some procedures, incl. stellate blocks, lower extremity peripheral nerve blocks and some trigger point injection sites

Adding non-particulate corticosteroid to local anesthetic is beneficial in cluster headaches but not in other headache types

Corticosteroid may provide additional benefit in TAP blocks and ilioinguinal/iliohypogastric nerve blocks in postherniorrhaphy pain; no evidence for pudendal nerve blocks

Minimal benefit for corticosteroids in trigger point injections
