Hyperhidrosis of the palms and soles

Sweating on the palms can make writing, handling tools, using screens, or shaking hands difficult. Sweaty soles may soften the skin, increase slipping inside shoes, and contribute to odour or irritation. The pattern may occur on both sides and may increase with heat, activity, or emotional stress. Cracking, redness, or a new rash should not automatically be attributed to hyperhidrosis; heat rash, intertrigo, or tinea versicolor can also affect uncomfortable skin areas.

Dry hands and feet carefully after washing, change damp socks, choose breathable footwear, and rotate shoes so they can dry. Use a gentle cleanser and avoid picking softened skin. A clinician may discuss antiperspirant applied to suitable skin, iontophoresis for palms or soles, or other options when sweating remains disruptive. Botulinum toxin injections can be considered for selected sites. Tell the clinician about cuts, eczema, implanted electrical devices, nerve problems, and medicines before iontophoresis or injections.

Arrange an assessment if sweating affects grip, walking, school, work, or social contact; causes repeated blisters or skin breakdown; or starts suddenly. Seek urgent help when sweating comes with chest discomfort, fainting, confusion, severe breathlessness, or marked overheating. New sweating during sleep or across the whole body also warrants medical review.

Is the pattern consistent with palmoplantar hyperhidrosis? Which option is safest for my skin? How should I protect cracked or irritated areas while treatment is considered?
