The location of where the nerves originate from your back are marked on the foot. Nerve pain in your foot may be coming from your back without the back ever being sore. For Example, the S1 nerve root innervates the lateral side of the foot and can give nerve symptoms (numbness, tingling, sharp, burning, etc) without ever producing back pain itself.
I have a pain that feels like a hot knife piercing the inside of my heal on my left foot every time I bend over to pick something up or tie my shoe I also have had lower back pain for quite some time. Could this be connected? Do you have any suggestions what this may be?
