First, thank's for your very important information. In Febuary 2021 I fell down 10 steps and shattered my elbow. The dr's used 12 screws and 2 plates to put my elbow back together. In Febuary 2022 they had to remove all the metal do to nerve damage being created. I developed crps from the elbow to the finger tips immediately. Since June the crps has expanded up to the side of my face. After trying several thing's like nerve block's with no help, my doctor want's to try the Abbott Proclaim XR SCS System nerve stimulater trial in about 2 week's. At this point I'll try anything to get some pain relief. 15-20% , like you, sounds wonderful at this point. Please comment about product and overall us for my condition. Thank's Darryl
