Peripheral Nerve Block
Medically reviewed by Drugs.com. Last updated on Apr 2, 2024.
A peripheral nerve block is anesthesia medicine given to numb a part of your body. You may not be able to feel pain in the nerve block area for about 4 to 18 hours. Until you have full feeling back, you are at risk for falls and injury. Be careful not to bump the numbed body part.
DISCHARGE INSTRUCTIONS:
Call your local emergency number (911 in the US) if:
- You have any of the following signs of a heart attack:
- Squeezing, pressure, or pain in your chest
- You may also have any of the following:
- Discomfort or pain in your back, neck, jaw, stomach, or arm
- Shortness of breath
- Nausea or vomiting
- Lightheadedness or a sudden cold sweat
- You have trouble breathing.
- You have a seizure.
Seek care immediately if:
- You develop swelling or hives.
- You have a severe headache or muscle twitching that does not go away.
- You have nausea or are vomiting.
Call your doctor or neurologist if:
- You have a fever.
- You feel faint.
- You have questions or concerns about peripheral 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. Change positions often. This will keep you from putting pressure on the area.
- Prop the area or surround it with pillows while you sleep. This will keep you from rolling over onto the area while you sleep. It will also keep you from putting 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:
Write down your questions so you remember to ask them during your visits.
