The itchy red bumps on your ankle and feet could be urticarial rash which is due to allergy
. Allergy could be due to any food products, drugs, cosmetics, insect bite or even emotional stress
. Urticaria is generally a mild condition and does`nt require any specific treatment. You may take an antihistaminic like cetrizine
and apply calamine
lotion locally as this is a soothing agent. If any allergens you are aware of, try and avoid them.
