4 months ago I began having trouble walking. It seemed to start out of the blue. I went in to the E.R. With terrific back pain. It was not in my spine, but about an once to the right of my low spine. Since then I have had 2 MRI's nothing found. I have had ocupunture from an MD to no avail, I have had treatment with the 10 machine which stops the pain at the time of use. My right leg has gone almost totally useless and my foot and part of my leg up half way up to my knee is cold. Still going to Dr's but so far no answers. I cannot walk now without a walker. It is very disheartening because 4 months ago I was 100% now I cannot do even my household chores, cook without sitting on a stool etc.
