Carpal Tunnel Injection
Procedure
Definition
A carpal tunnel injection delivers corticosteroid medicine into the carpel tunnel in the wrist.

Reasons for Procedure
The injection is done to ease pain and swelling in people with carpal tunnel syndrome. This is when the carpal tunnel is not wide enough and squeezes the median nerve that runs inside of it.
The injection may ease symptoms for 3 months or longer.
Possible Complications
Problems are rare, and all procedures have risk. Some problems may be:
- Infection
- Bleeding
- Injury to the carpal tunnel
What to Expect
Call Your Doctor
Call your doctor if you are not getting better or you have:
- Signs of infection, such as fever and chills
- Redness, swelling, more pain, bleeding, or any discharge from the injection site
- Pain that you cannot control with medicine
- New or worsening symptoms
If you think you have an emergency, call for medical help right away.
Prior to Procedure
Talk to your doctor about the medicines, herbs, and supplements you take. Tell the doctor if you have any allergies.
