Emma was 55 year old patient who was referred to me by another homeopathic doctor for a consultation. Thirty years earlier she walked into a closet and struck her head on a shelf. The pain was intense so she rubbed the top of her head vigorously to relieve the injury. From that point forward she continued to habitually rub her head. Soon, she began also rubbing her eyebrows to the point where she had rubbed off all of the hair on her eyebrows and the top part of her scalp. She had developed a condition known as trichotillomania. After 45 minutes of case taking I had only one reliable symptom that I could use: the sensation that her brain was rocking back and forth inside her skull.
