There is a syndrome called Charcot-Marie-Tooth disease, a genetically inherited disease that effects the long nerves in the feet. It is associated with a “cavus deformity” of the feet (high arches). This disorder causes the nerves of the feet to slowly malfunction. I do not have this disorder listed as a topic as of yet on the website so you will have to look it up under Google.
There are many other disorders that could also cause these symptoms. While most leg symptoms do originate from the back, there are still many leg related symptoms that do not. The next step might be an EMG/NCV test.
