Carpal Tunnel Injection

Carpal tunnel injections can help diagnose the source of pain and provide relief by delivering local anesthetic (numbing medication) and anti-inflammatory steroid medications into the median nerve space in the wrist. This procedure may calm inflammation, resulting in long-term pain relief.

  • We will contact you prior to your appointment to review medications you are currently taking, your medical history, potential risks and answer any of your questions.
  • Contact your doctor before you stop taking any medication.
  • If you have films, reports or CD-ROMs of any MRI, CT or X-rays you have already had please bring them to the appointment.
  • Please arrange to have someone drive you home after the procedure.
  • At your appointment, women should always inform their physician or X-ray technologist if there is any possibility that they are pregnant or if they are breast feeding.
  • Overall you should plan on approximately one hour of your time for this procedure from check-in until you leave the clinic.
  • Using X-ray guidance, our specialized staff will insert a thin needle and inject contrast solution into the nerve area of the wrist thought to be causing your pain. The contrast solution is designed to highlight your anatomy to make sure the nerve thought to be causing your pain is precisely targeted.
  • Then a combination of anti-inflammatory (steroid) and anesthetic (numbing) medications is injected into the area causing you problems.
  • You may experience some slight pressure or discomfort during the injection; you may be asked how these symptoms differ from your usual symptoms.
  • You may be asked to wait an additional 30 minutes after the procedure so that the clinic staff can monitor your symptoms before you leave.
  • You may experience numbness and/or relief from your symptoms after the injection.
  • Your usual symptoms may then return and possibly be worse than usual for a day or two. The beneficial effects of the steroids usually require two to three days to take hold, but may take as long as five to seven days. Every patient is different and your results may vary.
  • If there is no change in your symptoms after a week, your doctor may want to investigate other possible sources for your pain.
  • You may be asked to keep track of how long relief lasts and report it to your physician; this information is useful to them when considering next steps.
    • If there is no change in the pain, then your physician can focus on other possible sources.
    • If the injection blocked your pain effectively, but only for a short time, your physician may request additional injections or consider a procedure that offers more permanent relief.

Although complications are rare, we will review possible side effects and risks with you prior to your exam so you can ask questions and decide if this exam is right for you.
