Hello Thank You for contacting HCM. Most probably this is an allergic response. You might have bitten by some insect or some shoe has done this allergy. I would recommend you to try following: try to wear open shoes so that skin is not covered. use cetirizine one at night for 5 days for itch. Apply fusicidic acid 2% ointment over the skin twice daily Wash hands before and after applying. Keep it clean It will start resolving by itself in 2-3 days. Report to hospital if: Condition remain same after 2-3 days Any unusual symptom appears Condition deteriorates. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. Wishing you good health.
