A: Lidocaine is an anesthetic or numbing agent when used topically or injected in the spinal column, and it is an antiarrhythmic (helps with irregular heart beats) when given intravenously. When it is used topically on the skin, it works by inhibiting the nerve impulses that pass along pain signals to the brain.
Treatment â Along with the numbing medicine, the injection includes a corticosteroid to reduce inflammation, improving joint movement and providing long-term pain relief. Fluoroscopy (x-ray) is used in hip joint injections for guidance in properly targeting and placing the needle, and for avoiding nerve or other injury. The physician will inject contrast dye to confirm that the medicine goes into the joint, and then the medicine is slowly released into the joint.
