I would have to agree with your neurologist that you seem to be having a case of peripheral neuropathy, and the MRI seems to confirm this.
Has any testing been done for this, like an NCV 9nerve conduction velocity).
Peripheral neuropathy can have a large number of causes and can lead to the symptoms that you have described.
