Hives on the foot: symptoms, care, and warning signs

Foot hives can appear on the sole, top, toes, or around the ankle. They may follow pressure from shoes, heat, sweating, exercise, a new product, a medicine, food, or an infection. Welts commonly blanch when pressed and may change over time. A hive is usually itchy rather than scaly, cracked, or filled with fluid. The wider condition is called [Hives](/conditions/urticaria/). If the foot becomes puffy, read about [Skin Swelling](/symptoms/skin-swelling/); swelling can extend beyond the visible welts. Persistent one-sided redness with warmth, pain, or fever needs assessment because it may not be urticaria.

Loosen or remove footwear and socks that press on the area. Rest the foot, keep it cool, and apply a cool damp cloth for brief periods. Avoid vigorous rubbing and do not apply a product that has triggered skin irritation before. Record what touched your foot and what you ate or took before the flare, including the timing. A clinician or pharmacist can advise whether [Antihistamine Treatment](/treatments/medical-dermatology/oral-antihistamine-therapy/) is suitable. Do not share or use prescription steroids without guidance.

Get emergency help for breathing difficulty, dizziness, collapse, throat tightness, or swelling of the tongue or lips. Obtain urgent advice if swelling progresses quickly, makes walking difficult, or follows a suspected food, medicine, or insect exposure. Arrange a clinician visit for repeated episodes, a rash that stays fixed, significant pain, fever, bruising, or skin changes that do not improve.
