Hello, I am sorry to hear about what happened to you. You are correct about what you read about human bites. The human mouth has many bacteria and human bites have a very high risk of becoming infected. Hopefully, if the skin was not broke bacteria did not enter into the area. However, if the area around the bite is becoming red or swollen I would be concerned about an infection. Neosporin is a triple antibiotic cream however if bacteria entered the face this will not help. I recommend that if this does not improve and continues to worsen that you should be evaluated by a medical professional and possibly be put on antibiotics. I know it can be hard without insurance, but there are urgent cares and MECs that may be able to give you a discounted visit and the antibiotics for treating these are generic and inexpensive. Good Luck and Take Care
