The first step of the transforaminal injection treatment is applying a local anesthetic to the treatment area. This helps to relieve any discomfort that may occur during the injection process. Once the skin is numbed, we will use ultrasound technology to carefully insert a needle into the appropriate opening in the spine where a nerve root is found. Once properly positioned, the injection will be performed and the treatment will be complete. The full treatment takes less than an hour to perform. You may experience some soreness or bruising after your treatment, but these effects will fade within a few days.
