Assuming that you’re not overweight, don’t suffer from a thyroid problem and that you’re in good general health, you might be suffering from hyperhidrosis. This is basically excessive perspiration due to overactivity of the sweat glands.
For localised hyperhidrosis, a 20 to 25% solution of aluminium chloride hexahydrate in absolute ethyl alcohol applied at night to the dried axillae, palms, or soles and covered tightly with a thin polyethylene film is usually effective. In the morning, the polyethylene film is removed and the area is washed free of salt. Two applications usually protect the area for 1 wk. If the aluminum chloride under occlusion is irritating, it should be tried without occlusion. This solution should not be applied to inflamed, broken, wet, or recently shaved skin.
