Hello Dr. I was diagnosed in October 2013 with sacorilyitis and arthritis in my left hip. I ve been going to a chiropractor since Nov 2013,. The pain which comes and goes in my lower back is not any better. I use the wobble chair 3xs wk for to minutes. I know everyone is different, but, how long should it take to be feeling better. The pain us worse in the morning, or I m waking in the middle of the night in pain. It seems worse when my bladder or colon is full, or when I stand fir too long. Is there something else I can do.
