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:
- No improvement in symptoms
What to Expect
Your doctor may ask you what medications you take and if you have any allergies to medications.
You will be given an injection of local anesthetic to numb the area.
A needle will be filled with corticosteroid medication. This medication calms inflammation. Your palm will be facing upward. The inside of your wrist will be cleaned. The needle will be inserted into the carpal tunnel area of the wrist, and the medication will be injected.
You may feel some pain after the anesthetic wears off.
The injection site will be bandaged. You and your doctor will discuss what to expect in the coming days.
When you return home:
- Take over-the-counter pain medication.
- Avoid strenuous activity involving the joint for 48 hours.
- Follow your doctor's
Call Your Doctor

- Signs of infection, including fever and chills
- Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
