Thanks gcoe for your kind reply. I would also consider whether this currently situation is truly worse that the recovery you had previously. If things we a lot better than they are now and have regressed then perhaps there is something additional going on again at that level. Perhaps it is worth another scan if this is the case so long as their is something post the last intervention to compare it to. An easier route also may be to repeat nerve conduction studies from post op with now (again only if you have something for that comparison). It would be nice to see if things are actually different.
