Probably not ...: Dyshidrotic Eczema, sometimes called Pomphoylx is an itchy skin condition of the hands and feet, characterised by vesicles, fluid filled bubbles. Causes are unclear and probably multfactorial; genetic predisposition (can run in families); triggered by stress, sweating, humdity or irritants; associated with contact allergy such as nickel. No clear association to Agent Orange exposure.
