I have spent the past 3+ years in pain trying to delay surgery. Started falling around Thanksgiving, have weakness in both legs, very "brisk" reflexes and significant tremors. Scheduled for L4-5 posterior/anterior fusion with bone graph. Surgery originally scheduled 12-23-09, then 2-8-10, delayed due to insurance. Surgery is now scheduled 2-26-10. In the past 2 months, I have gotten significantly weaker, I have to limit walking as the siatic nerve "catches" on the jagged edges of the bone. I am so concerned about recovery as I am so weak with poor endurance. I understand that my pain may never go away, although I pray daily that it will. I would love to get my leg strength and coordination back> My surgeon thinks there may be something neurological going on (like MS), wants a work up done, but I want to recover from the fusion first! Any insight you all have will be greatly appeciated!
