Sympathetic Nerve Block
Medically reviewed by Drugs.com. Last updated on May 6, 2024.
A sympathetic nerve block is an injection of anesthesia medicine around nerves near your spine. You may need a sympathetic nerve block to locate an area of pain or to relieve nerve pain. It may also be used to control heavy sweating or relieve Raynaud syndrome. Your healthcare provider may recommend a series of nerve blocks if your pain or condition improves after the first.
DISCHARGE INSTRUCTIONS:
Call your local emergency number (911 in the US) if:
- You have a seizure.
- You have trouble breathing.
Seek care immediately if:
- You develop hives or swelling.
- You have severe pain.
Call your doctor or neurologist if:
- You are dizzy or have ringing in your ears.
- You feel numbness or tingling around your mouth.
- You have numbness or weakness in a limb 8 hours or more after your procedure.
- You continue to bleed at the site of the needle insertion.
- You have questions or concerns about sympathetic nerve blocks.
Self-care:
Your healthcare provider may give you specific instructions. The following are general safety guidelines:
- Rest the day after the nerve block. Your provider will tell you when you can drive and return to work or your normal daily activities.
- Keep pressure off the area. Prop the area or surround it with pillows while you sleep. This will keep you from rolling over onto the area. Change positions often to keep you from putting direct pressure on the area.
- Protect the area from injury. Move slowly and carefully so you do not bump the numbed body part. Do not touch anything that might be hot. You might not feel the skin burn until it is severe. Protect the area in hot and cold weather.
- Keep a record of your symptoms and activities. Include the date if your symptoms return.
Follow up with your doctor or neurologist as directed:
Bring your symptom record to your follow-up visits. Write down your questions so you remember to ask them during your visits.
