I will be having a two level fusion at the end of July or first week in August. I believe it was S1 and L4-5. Anyway say the surgery is somewhat successful and I have recovered etc.. I know this stops movement in that area. What I really do not understand will be the restrictions and limitations afterwards. What kind of things can you not do because your lower spine no longer moves? Not what can't I do because of my pain, but just because of the fusion itself. Can everyone who has had one give me some input on limitations once your lower spine is fused? Are there things you just cannot do anymore? Are there limits on lifting after you heal and fuse? Can you not bend over? What about sitting? Sex? Sorry but just want to know how this will affect my life after healing. Thanks!
