Cervical Nerve Block and Steroid Injection
A cervical nerve block and steroid injection can be performed to determine whether a particular nerve is causing neck, shoulder, arm or hand pain, and it also provides temporary pain relief. While these goals are usually successful, Radiology Associates of Wausau cannot guarantee that the cause of your pain will be identified or that your pain will be decreased.
What to Expect
The procedure takes about 30 minutes. The radiologist will use fluoroscopy to pass a needle next to the nerve that is believed to be causing pain. Two different medications will be injected. The first, a short-acting anesthetic agent, is injected for diagnostic information. Pain relief from this medication will wear off in about 1 – 2 hours. The second medication—an anti-inflammatory steroid—will provide longer-term pain relief and will begin working after 1 – 2 days.
During the injection you may feel pressure or tingling. These sensations last several seconds and can provide important diagnostic information. After the procedure, the short-acting anesthetic can make your arms feel numb or weak for a few hours, so you should minimize activity for 2 – 3 hours. You can leave immediately after your procedure is performed if you have someone to assist you home.
