question: I am losing my balance alot and have fallen several times. I had back surgery 5 years ago and got MERSA and could not even turn over in bed for a year. I worked hard with the therapy they gave me I did not want to end up in wheelchair all the time, but in the last few months my balance has gotten really bad, I feel like it is all I can do sometimes to just stand up, and it is worse at night. I am numb in places in my back and on my legs. What is wrong?
