Comfort Help: Injections (invasive)
More recent reviews indicate pain management programs relying spinal injections and analgesic drugs shows no better than usual care for improving functional outcomes (Guzman`02). Absent radiculopathy, back pain is not improved by epidural glucocorticoids or anesthetic Injections. With or without radiculopathy injections into lumbar disks, lumbar facets, and trigger points show little promise (Nelemans`01, Khot`04). Radiofrequency ablation of facet joints small nerves moderate effect lasting for only 4 weeks(van Kleef`99), and in another trial ineffective(Leclaire 01).
