Nerve injury can be significant and can cause pain and functional impairment. Following the accurate diagnosis of which nerve or nerves is/are affected, a nerve block can be performed to reduce inflammation and pain. A nerve block can also be performed to help make a more accurate diagnosis of which nerve or nerves is/are affected.
Nerve blocks can be safely and accurately performed using either ultrasound or fluoroscope guidance. A mixture of medications will be used to block the nerve, including an anesthetic and a long-acting steroid.
After Your Injection
- Following a nerve block, you may experience soreness for one to two days; the soreness is minor and can be treated with local ice application. Rarely, one will experience an increase in symptoms following this injection. The average time it takes to begin noticing pain relief ranges from immediate to three days, and the average length of time nerve blocks provide relief is several weeks to several months. Results can vary widely and depend on several factors.
- Numbness and weakness in the distribution of the blocked nerve may be noted for up to 16 hours.
- You may return to work or school the day following your injections. No additional time off will be necessary.
- If you are a diabetic, please know that your glucose levels may rise temporarily. Consult your PCP or endocrinologist if your glucose levels rise higher than 200 mg/dL or remain slightly elevated for more than three days as you may require coverage with a different medication.
