Describe the symptoms of the local forms of hyperidrosis.

The essential, and frequently the sole symptom, is more or less profuse sweating.

If the hands are the parts involved, they are noted to be wet, clammy and sometimes cold.

If involving the soles, the skin often becomes more or less macerated and sodden in appearance, and as a result of this maceration and continued irritation they may become inflamed, especially about the borders of the affected parts, and present a pinkish or pinkish-red color, having a violaceous tinge. The sweat undergoes change and becomes offensive.

Is hyperidrosis acute or chronic?

Usually chronic, although it may also occur as an acute affection.

What is the etiology of hyperidrosis?

Debility is commonly the cause in general hyperidrosis; the local forms are probably neurotic in origin.
