A few years ago, a lady came to our practice. She told me in a preliminary telephone conversation that she was terrified of falling. As soon as she entered the hallway, I noticed she was leaning against the wall, looking for support. When she entered the treatment room, she grabbed the nearest chair back and held on to it convulsively. When asked about this, she told me she was suffering from giddiness. For years, she would go from one doctor to another without anyone being able to help her with this problem.
