I hope your recovery goes well. I have an L4,L5, S1 fusion along with a “Jack” as the doc called it to go where my L5 was crushed. I regret doing it, as it only made it worst. I’d try to get some PT if able to. I think that is my issue. Doc said to walk, so I did. Others I know that did it with other doctors went to PT and saw better results.
