My Mother Is Having Chronic Leg And Back Pain. She

My mother is having chronic leg and back pain. She had 3 surgeries on her lower back because of deteriorating discs. The pain continues despite ring treated through pain management. Her latest exam has determined that the pain is coming from the deteriorating of her tailbone in which the pain radiates down her leg. She skeptical of having the surgery because the last recover was long painful and unsuccessful. What can you tell me about the surgery and recovery.
