I got a small sore spot on the inside of my lower lip. I've gotten this before. I used both Orajel and Anbesol (probably more than I should have) as well as Orajel mouthwash. I seem to have some side effects but I don't think they are life threatening. There is some swelling on the sides of my tongue and it's a little sore. I have white sores on the sides of my mouth behind the molars, between top and bottom. I'm having trouble trying to clear my throat (feels like a drink went down the wrong way and I can't cough it out - it's very uncomfortable). There is nothing like difficulty breathing, dizziness, cyanosis or headaches. Do these symptoms sound like an allergic reaction to benzocaine?
