Primary focal hyperhidrosis is not caused by another medical condition nor is a side effect of medications. The excessive sweating itself is the medical condition. The excessive sweating is specific to only individual areas of the body and is characterized as being symmetrical, meaning that it affects both sides of your body in the same way (both feet, both hands, both underarms, etc.). Some people may experience the excessive sweating on multiple focal areas such as both hands and feet (palmoplantar hyperhidrosis).

Palmar, plantar and palmoplantar hyperhidrosis are the most common forms. The palms of your hands and the soles of your feet have more sweat glands than other body parts which explains why it is so common. Many of those who have this medical condition describe it as having clammy hands and feet.
