Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have symptoms of pus filled blister on lip which are pointing towards to condition an allergic reaction or infection. The allergic reaction can occur due to various reasons like food allergy, allergy from toothpaste or other dental product or excessive exposure to sun. Infection can be bacterial or viral. Need not worry. I would suggest you to take over the counter antihistamine Chat Doctor.
