Hi Dear, Welcome to HCM. Understanding your concern. Thanks for your query . The symptoms you mention in query in pointing towards allergic reaction due to insect bite . I would suggest you to :- - Give cold compresses to affected area 2-3 times a day . - Take over the counter antihistamine drug like benadryl or zyrtec. . - Drink plenty of fluid , drink at least 8 glasses of water in a day . - Do not touch the affected area with your hands as it can aggravate condition. I condition doesn t get better in a day then consult dermatologist for proper examination and to rule out other cause like trauma , angioedema or pimple . Doctor may prescribe antibiotics and steroid ointment. If the allergic reaction is severe then doctor may give adrenaline short . Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
