sweating problems are common in fm because of the autonomic nerve dysfunction. the sweat glands receive nerve supply from specific autonomic nerves called sympathetic sudomotor nerves. sweating regulates our body temperature (called thermoregulation). in fm dysutonomia is present and causes too much sweating usually but sometimes the opposite occurs and our skin can be too dry. throw in the usual suspects that overstimulate our autonomics: weather changes heat sunlight certain meds esp ssri's & snri's position changes i. e. laying down stress exercise attempts etc. and we become bona fide sweating machines! treatments for excessive sweating are limited. i advise my patients to avoid aggravating factors if they can use antiperspirants not deodorants and sometimes an anti-cholinergic medicine can be tried. work with your doc.
