Herniated disc/ rupture disc discectomy or fusion surgery

i personally want to know of anyone you know of in the profession that has suffered any of these injuries. And success stories. Im suffering from severe back issues and am being givin bleek hope from doctors. I know there has to be some strong well built machines out there who have been through this. Just want to hear about em for some motivation and if you know them personally how did they go about recovery and training post injury.
