Hello Thank You for contacting HCM. Insect bite results in allergic reaction which is manifested in the form of rash with or without itching. It takes few days to recover. I would suggest you following things: Take levocetirizine one at night for 5 days. Try not to scratch the area or it might lead to scar formation. try to keep your body covered while working outside. 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.
