 This is a 58-year-old male who reports a six to eight-week history of balance problems with fatigue and weakness. He has had several falls recently. He apparently had pneumonia 10 days prior to the onset of the symptoms. He took a course of amoxicillin for this. He complained of increased symptoms with more and more difficulty with coordination. He fell at some point near the onset of the symptoms, but believes that his symptoms had occurred first. He fell from three to five feet and landed on his back. He began seeing a chiropractor approximately five days ago and had adjustments of the neck and lumbar spine, although he clearly had symptoms prior to this.
