What is a Nerve Block?
A nerve block involves injecting anesthetic medication, sometimes combined with steroids, near specific nerves to block pain signals from reaching the brain. These procedures are commonly used to diagnose the source of pain or provide temporary relief for conditions such as sciatica, chronic migraines, or complex regional pain syndrome.
This procedure helps to:
- Temporarily block pain signals.
- Reduce inflammation around nerves.
- Improve function and mobility.
- Provide diagnostic insight into pain origin.
- Allow patients to participate in rehabilitation.
What to expect after a Nerve Block?
Pain relief often occurs immediately due to the anesthetic, though it may wear off in a few hours. The steroid component, if used, takes longer to show effect. Some numbness or weakness in the affected area may occur temporarily.
- Immediate pain relief that may be temporary.
- Numbness or weakness in the treated area.
- Gradual longer-term relief if steroids are included.
- Quick outpatient recovery.
- Relief lasting days to months depending on condition.
