Hand sweat may occur independently or in combination with sweating of the armpits, face and scalp, or feet. Facial blush may also be present. This condition causes severe dripping sweat from the armpits. Excessive sweating of the feet is the result of over-stimulation of the sweat glands in the feet by the sympathetic nervous system.
Facial blush is caused by overstimulation of the sympathetic nervous system.
Facial blush is caused by overstimulation of the sympathetic nervous system. The mechanism is involuntary and anxiety may aggravate it, but the facial blush may also occur with or without stress or anxiety. Patients with this condition were born to blush excessively. Physiologic blush occurs more frequently in some individuals than others but generally occurs only in special situations, coming on quickly and fading rapidly. Individuals with facial blush, with or without facial hyperhidrosis, characteristically experience a glowing red face that occurs more frequently than physiologic blush.
