Pelvic imbalance is the most common condition in the lower back region. Poor posture, overweight, lifting incorrectly, poor daily habits, and weak core cause the muscles to become imbalanced and weak. This is what causes chronic back pain, disc herniations, disc bulging, degenerative joint conditions (osteoarthritis), inflammation, sciatica, mid back pain, neck problems, along with hip and knee complications. When pelvic imbalance occurs other areas within the body start to compensate.
