I had in July 1,2009 anterior and posterior interbody fusion on L3 to S1, with instrumentations. The surgery went very well, I staid in hospital just 3 days because I was able to walk , up to stairs without dizziness or other problems. Thank God everything was very easy, easier that I expected, but after few days at home my legs 's muscle seems stiffness.it's hard sometimes to walk because that pain in both legs. I was worry developed blood clot or other problems. Did somebody has the same experience with legs like me? thanks !
