Did you know HORMONE IMBALANCE can cause BACK PAIN? Many women are aware of this after experiencing low back pain during menstrual cramping, but did you know it can continue to be the cause even while not on your cycle? Applied Kinesiology has identified muscles around the hips and inner thighs that hold your back, hips, and pelvis together react to reproductive organs. Men make hormones too and if there are imbalances from stress, medications, diet, or genetics then the repercussions could be an unstable pelvis which leads to a weak and sore low back.
