Cramps are most commonly seen in the legs and feet; in particular the calf muscle although any muscle in the body can be prone to cramp. Pain, stiffness or numbness in the legs or feet is usually the result of compression in the lower back and so it is vital that any body stress in this area of the spine is released.
When this stress is allowed to continue unresolved, nerve pathways radiating out from the protected area lose their natural/normal state of function. The electrical action of the nerves leads to either HYPO or HYPER activity whereby the breakdown in communication to the motor nerves can lead to a hyperactive muscle.
By attending to the lower back through releasing the tension on the nerve pathways, communication is restored back to normal and the correct balance can return to the motor nerves so the cramps disappear altogether.
