Dr V. question

I just ordered a box of foot pads for the first time. I have alot of left foot pain around maybe the lung or heart area according to your chart. I have troubles taking deep breaths often.
Does the breathing cause the foot pain? Or does the foot pain cause the breathing problems?

Also, can I just use the pads on my left foot everynight since that is the foot that hurts? Or should I still alternate feet?

Thanks
