The only perma fix for mine is supposedly a disc “Fusion”, where they carve 4 pieces of bone from somewhere, (or IIRC, use “donor” bone… wtf?), and use them like splints to glue the discs together.
I so far haven’t opted for it, because it takes so damned long for the splints to grow into the discs & become strong, so recovery is something in the order of 6 - 8 months before resuming normal activity. Is that what you are talking about Digs??
Or, has anyone else had this done?
