Types of tail bone issues described by patients when consulting our office were: Ache, Tightness, Burn, Tingling, Numbness, Tenderness, Sharp, and/or Stabbing. Between February 2002 and August 2004, 10 people who suffer from the above kinds of tail bone issues completed the initial 6-8 week period of care in our office. Of these 10 people, 6 (60%) of them reported a 70 – 100% improvement and none reported no change in their complaint within 8 weeks of their first upper cervical adjustment (1 person (10%) had a 10-40% improvement and 3 (30%) had a 40-70% improvement).
