Make SURE you get a nerve catheter for pain as anesthetic. I had reverse replacement in October and the nerve catheter stayed in for 6 days...meaning no need for other pain meds. You just need help removing it...You wear a plastic round thing around your neck filled with the nerve block meds. You control how little or how much you use. I used very little so it would last longer. I'm 68. Let me know if you need more information.
