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:
