You may sweat so much that it soaks through your clothes or drips off your hands. Besides disrupting normal daily activities, hyperhidrosis can cause social anxiety and embarrassment. Hyperhidrosis treatment usually involves prescription-strength antiperspirants on the affected areas. Rarely, an underlying cause may be found and treated. For persistent hyperhidrosis, you may need to try different medications or other therapies. In severe cases, your doctor may suggest surgery either to remove the sweat glands or to disconnect the nerves responsible for the overproduction of sweat...consult your doctor they will help you

Sweating is your body's mechanism to cool itself. Your nervous system automatically triggers your sweat glands when your body temperature rises. Sweating also normally occurs, especially on your palms, when you're nervous. In hyperhidrosis the nerves responsible for triggering your sweat glands become overactive and call for more perspiration even when it's not needed. With stress or nervousness, the problem becomes even worse. Often there is no underlying cause of heavy sweating; this condition is called primary hyperhidrosis. This type usually affects your palms and soles and sometimes your face. It may have a hereditary component, because it sometimes clusters in families. If the sweating can be attributed to an underlying medical condition, it's called secondary hyperhidrosis. This type is more likely to cause sweating all over your body. The goal of treatment for hyperhidrosis is to control your heavy sweating. Once any underlying medical conditions have been addressed or ruled out, treatment will depend on the severity of the problem. Sometimes you may need to try a combination of treatments.  Consult Pediatrician...
