Carpal Tunnel Injection
by Krisha McCoy, MS
A carpal tunnel injection is a corticosteroid injection into the carpel tunnel area of the wrist.
Reasons for Procedure
The median nerve runs from the forearm into the hand. Carpal tunnel syndrome occurs when this nerve is squeezed at the wrist as it runs through the carpel tunnel. This results in pain, weakness, tingling, or numbness in your hand and wrist. Pain may also radiate up your arm.
Steroid injections into the carpel tunnel area can help improve symptoms for 3 months or longer. You may not need further treatment.
Complications are rare, but no procedure is risk-free. Your doctor will review a list of possible complications which may include:
