    ### Response:
    Small fiber neuropathy is a condition characterized by severe pain attacks that typically begin in the feet or hands. As a person ages, the pain attacks can affect other regions.

The attacks usually consist of pain described as stabbing or burning, or abnormal skin sensations such as tingling or itchiness.
