During the procedure, you will be given either general anaesthesia or a spinal block. Under general anaesthesia, you will be asleep during the procedure and will feel no pain. With a spinal block, the lower half of your body will be completely numb, but you will be otherwise awake and alert throughout the procedure. During recovery, there will be pain and your doctor will be able to assist with pain management. How much pain there is and how long it lasts varies from patient to patient and depends on the amount of physical therapy involved in your recovery.
