We walking talking frequencies!

As we know, we are frequencies!

I think this helps to explain a little more about pain and frequencies on a cellular level.

Low energy- means you’re losing electrobiochemical capacity to produce energy- this can result in pain.

So why are frequencies important in pain?
Nerves transmit an electrical signal or action potential, the signal travels along the nerve (axon).
On a cellular level the action potential is created via the opening and closing of pain related ion channels, which allows for the redistribution of charged ions on the nerve cell membrane (cell wall).
Simply, ion channels are made of different proteins, there is a complex series of events that occurs in order to open and close the ion channels, and move the charged particles (ions) across/ through the cell wall.

Sodium channels appear to be the most critical for pain transmission along nerves, as proteins in the ion channels mediate voltage- dependent ion permeability of excitable nerve cell membranes. Sodium is in higher concentrations outside of the cell, with potassium higher inside the cell, and Calcium preferring to remain in the cell membrane. Therefore there is a negative charge inside the neurons and a positive charge outside of the neurons. (Potassium helps to conduct proton currents within the cell).

A different response of opening of closing ion channels occurs relative to the voltage difference across a cell membrane. The proteins form a sodium- selective channel through which sodium ions pass relative to the electro chemical gradient. When the charge within the cell becomes less negative, the channel opens and allows ions to cross the membrane.

This is where the discs come in… they provide the stimulus (voltage) and the appropriate frequency to stimulate the neuron. Energy in the form of ATP is required to transfer extracellular molecules to intracellular (sodium- potassium pump)- the energy of the nerve depends on this pump. (When ATP is low we crave carbs!). 
If you think of the disc as the voltage, the current is the neural pathway/ oscillatory pattern/ frequency and the resistance is inflammation etc., this may help to simplify things- the more resistance to flow from things like tissue damage/ damaged myelin sheath of nerve etc., the weaker the current (frequency). Also this is why dehydration slows/ impeded the performance of the discs- it increases the electrical resistance which means conduction and flow decreases.
