Foraminal infiltration is a medical technique of injecting an anti-inflammatory, corticosteroid
-based product at the spine
, where the nerve roots emerge. This procedure can be performed under the control of a scan in order to have the closest possible location to the nerve responsible for the pain
. These injections are performed under local anesthesia in people who suffer from a herniated disc responsible for neuropathic
pain like sciatica
. Unfortunately, the pain relief is usually temporary.
