What Causes Loss Of Balance After The Fusion Of L5 And S1?

Hi, may I answer your health queries right now ? Please I had L5 S1 fused with titanium rods and screws July 2004. Now my balance is gone, at times I loose strength in my legs. My back kills me and my hips. I never had back pain only since my surgeries. I am 44 and every day/nite is a challenge no one gets it.. They only try to compare me to someone else..I only wish I was that person. I resent my husband.. He does nothing to help with house work, but he is quick to complain. I fell last week and knocked myself out.. He put me in bed and told me when I woke up what happened. God forbid we have another med bill.
