You are correct in that abnormal sweat patterns are an indication of autonomic neuropathy. Mayo Clinic in Rochester MA does a sweat test as part of their workup for neuropathy. I think your pattern would be considered abnormal. You strip down to a loin cloth, lie on a cart, then they cover your body with a yellow powder. They wheel you into a room that gets very warm from infrared lamps. They monitor your heartbeat and body temperature, as I recall. If you sweat, the yellow turns to purple. I was normal except for some small spots on my toes that did not sweat. My mother hardly sweat anywhere.
