How else may nerve block injections be used for chronic pain?

Donna Hill Howes, RN
Family Practitioner

If pain continues despite other treatments, pain medications may be injected into the space around the spinal cord (intrathecal space). People who need constant pain relief may have surgery to implant a small pump to automatically deliver pain medication. Pain-relievers injected into the space around the spinal cord include opioids (such as morphine), corticosteroids, and the drug ziconotide.
