Numb Heels

[Ray]

Could possibly be a nerve issue.
Compressed nerve in the lower back from a bulging disk or calcium build up.
Compressed nerve in the leg area from a tumor or growth. This happened to
a coworker who just died from cancer last month. His leg was numb and he thought
had a back problem, it turned out to be a maglignant tumor in the leg pressing
against the nerve that runs down the leg.
Or a blood flow issue, like diabetes or something similar.
