Most Lower Back Issues are related to the following Muscles: Gluteus (Maximus, Medius and Minimus)
Piriformis Psoas Iliacus Rectus Abdominus Quadratus Lumborum
Deep Massage and Triggers can relieve a majority of the Pain and Issues.
A majority of the time relief from Sciatic Issues can be relieved from Triggering the Quadratus Lumborum, Gluteus Minimus and Piriformis Muscles followed by a Great
Stretch of the Hip / Pelvis Joint. I have had clients receive relief from as little as a Couple Days to never having Sciatic Pain again, results are individually based.
