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.
