Small Fiber Neuropathy-caused by Lumbar nerve damage?
I have Idiopathic Small Fiber Neuropathy confirmed May 2012 by skin biopsy.
I had a Foraminotomy in 2007 because of Sciatica pain in my right leg, shortly thereafter I had numbness and needle pricks in my right thigh, the Neurological surgeon said it would go away in the near future, yeah right!
In March, this year, after severe Sciatica nerve pain I had L3, L4, L5 fused by a Orthopedic Surgeon. Shortly thereafter I had numbness and needle pricks in both legs and burning feet.
The Neurologist I am now seeing said he doubted the SFN could be caused by damage to the Lumbar nerve. He told me to buy Metanx and come back in 2 months, the Metanx has done nothing, nor did Gabapentin.
Since he has not found the cause of the SFN I can only guess it is most likely nerve damage or nerve compression in the Lumbar region.
Are there any tests that I can politely suggest to him that will confirm or reject my opinion?
