Hand, foot and mouth foot rash: what to know

The spots may be flat or slightly raised, and some become fluid-filled blisters. They can be tender, warm, or mildly itchy. The foot findings may appear with fever, sore throat, reduced appetite, or painful sores inside the mouth. Skin colour can change how redness appears, so location, texture, and the presence of blisters matter more than colour alone. A foot rash has many possible causes; other conditions such as Atopic Dermatitis, Contact Dermatitis, Drug Rash, Heat Rash, Intertrigo, Psoriasis, Ringworm, or Scabies can look different and need separate assessment.

Wash hands after touching the rash, keep blisters clean, and avoid picking or popping them. Use loose, breathable footwear and change damp socks. Cool fluids and soft foods may be easier if mouth sores are present. A pharmacist or clinician can advise on age-appropriate relief for fever or discomfort; do not give aspirin to children. Avoid sharing cups, towels, utensils, or footwear, and clean frequently touched surfaces.

Arrange prompt medical advice if a child cannot drink, urinates much less than usual, seems unusually sleepy, or has worsening mouth pain. Seek urgent care for trouble breathing, severe drowsiness, a stiff neck, a rapidly spreading painful rash, pus, or skin that becomes increasingly swollen and hot. A clinician should also assess a rash in a very young infant, a person with a weakened immune system, or anyone whose symptoms are not settling.

Could the foot lesions fit hand, foot and mouth disease, or do they suggest another rash? How should we protect the skin if a blister opens? What signs of dehydration should we watch for? When can the child return to nursery, school, swimming, or sports?
