Generally, Leg or foot numbness can be related to:
Lumbar Spinal Stenosis
Lumbar spinal stenosis is a narrowing of the spinal canal in the lower back. Stenosis, meaning narrowing, can put pressure on the spinal cord or the nerves that connect the spinal cord to muscles.
Familial amyloid polyneuropathy (FAPs) are life-threatening, multisystem, inherited disorders where amyloid (an abnormal protein that can be deposited in any tissue) accumulates in nerve fibers and around nerves.
Narrowing of the canal surrounding the nerves. It can be caused by normal wear and tear of the spine or by a previous injury to the region.
Ossification of the Ligamentum Flavum (OLF)
