An anesthetic injection is a diagnostic procedure to confirm that the area injected is the cause of your symptoms.
What to expect during the procedure:
- You may be asked to remove your pants or shirt and you will be given a gown to wear.
- The exam room is usually dark so the images can be seen clearly on the computer screen.
- The technician will move a small wand (transducer) over the area to be imaged. A warm, clear gel will be placed between the transducer and the skin to facilitate the transmission of the sound waves into and out of the body.
- Your skin will be cleaned.
- You may be given topical anesthetic which will feel very cold.
- Local anesthetic will be administered under the skin.
- Local anesthetic will be administered into the area of interest using ultrasound for guidance and confirmation.
What to expect after the procedure:
- The anesthetic lasts from 1-4 hours after.
- It is important for you to determine if your pain has been relieved during the 1-4 hours following the procedure during which anesthetic is active.
What types of activity are allowed after the procedure:
- If your doctor has given you instructions please follow his or her recommendations.
- Please do activities which normally cause your symptoms following the procedure.
