Mid/lower back pain is almost always caused by muscle imbalances. They are usually the most difficult issues to resolve and usually involve the hips. The mid/lower back is in use at all times except when laying flat on the back and it is absolutely necessary to start postural exercises daily to balance the muscles. Mid /low back issues are resolved by releasing the muscles along the spine and then in the hips with structural function exercises being given. In these cases the first session is usually11/2 hours long with others being 1 hour long and *average of 7- 9 sessions being needed.
