It is the subspecialty of medicine that deals with treating pain using precision-guided injection techniques to deliver pain-relieving medicine to specific areas of your body. The doctors who perform these procedures are trained for one or more years in pain medicine and are board certified. The injections are typically done using X-ray, Ultrasound or CT scan control. It involves blocking nerves to diagnose the exact source of pain. This helps us to plan further management. These injections are also done in the joints and in the discs between your spine bones. The medicines used in the injections are mainly local anaesthetics. Following diagnosis, we use radiofrequency current to stun the nerves carrying pain impulses.
