Phantom sweating: a novel autonomic paresthesia.

OBJECTIVE

To describe the biology of phantom sweating, a novel autonomic neuropathy symptom, based on a description of a patient with a small fiber and autonomic neuropathy.

METHODS

Clinical and laboratory assessments.

RESULTS

Evidence of a generalized small fiber and autonomic neuropathy.

INTERPRETATION: Phantom sweating occurs frequently after sympathectomy but has not been reported previously in patients with a somatosensory or autonomic neuropathy. We suggest that this symptom is an autonomic paresthesia.
