Peripheral Nerve Blocks

Your caregiver has placed a nerve block in one of your arms or legs to reduce pain and discomfort. The block lessens the amount of pain medicine you will need. Your caregiver will inject you in the arm or leg that was operated on. The injection is usually given away from the surgical site. The injection is a local anesthetic or a combination of local anesthetics. This injection provides numbing pain relief for up to 18 to 24 hours. There are few possible complications from this procedure. However, you should notify your caregiver if you have any problems.

Be aware that you may lose feeling at and around the surgical area. If numbness happens, take proper measures to avoid injury. Do not stand up unassisted if you have a nerve block in your leg. Do not try to lift items if you have had a nerve block in your arm. Be careful when placing hot or cold items on a numb extremity.
