That's a good question @kfrenc04. Spine problems can compress/damage nerves which can cause neuropathy symptoms. I'm no expert but I think it may help to keep asking questions in your discussions with your doctor or neurologist. Here are a few references if you want to read more about diagnosing small fiber neuropathy.

"Small-fiber neuropathy is generally underdiagnosed, according to Dr. Khosro Farhad, a neuropathy expert at Harvard-affiliated Massachusetts General Hospital. The problem is that routine neurological exams and tests cannot accurately discriminate between large-fiber and small-fiber neuropathy. "A skin biopsy is a gold standard for diagnosing small-fiber neuropathy; however, this test is not always available," says Dr. Farhad."
