Foot hyperhidrosis: causes and treatment options

Hyperhidrosis can make socks and shoes damp even when the surroundings are comfortable. Moisture may soften the skin, increase friction, and encourage odour or secondary irritation. Heat Rash and Intertrigo can develop where warm, wet skin rubs; other colour or scale changes may need a separate diagnosis such as Tinea Versicolor. Sweating may affect both feet, occur during waking hours, or accompany sweating elsewhere. A sudden change can have a medicine or medical cause and deserves review.

Wash and dry the feet carefully, including between the toes. Rotate breathable shoes, change damp socks, and use absorbent insoles if helpful. A clinician may recommend Prescription Antiperspirant and explain when to apply it to completely dry skin. Iontophoresis uses a mild electrical current through water and may be considered for hands or feet. Other options include Botox For Sweating or Microwave Sweat Gland Treatment, depending on the diagnosis, treatment area, and response to simpler measures. Do not apply a strong product to cracked skin without advice.

Book an assessment when sweating interferes with work, sleep, sport, footwear, or social activities, or when home measures are not enough. Seek prompt care if sweating starts suddenly with chest pain, faintness, breathlessness, confusion, or feeling acutely unwell. Painful cracks, marked redness, swelling, odour with drainage, or a new rash also need examination because moisture can coexist with infection or inflammation.

Is this primary foot hyperhidrosis or could a medicine or health condition be contributing? How should I use an antiperspirant safely? Would iontophoresis suit me? What skin changes should prompt an earlier review?
