It's been about 3 months since my double fusion in the lower back and when I went to my Neurologist yesterday he said he may have to remove the screws from the double fusion he did. The fusion is coming along well, but I'm having allot of pain still. Anyway, how is a surgery done for removing the screws from a cage and also removing the bone stimulator. Will I be put to sleep? Will I have to stay in the hospital?
