Hello Thank You for contacting HCM. In my opinion the symptoms are suggesting allergic reaction. Did symptoms appear after taking some particular food, insect bite? If yes then these are most probably because of allergy. Following measures will help to reduce the severity: cetirizine one at night for 5 days. Avoid scratching else scar may form. Report to hospital if: Condition remain same after 2-3 days Any unusual symptom appears Condition deteriorates. There is difficulty in breathing. 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.
