I have a small light brown blister on the top right side of my lower lip that I woke up with this morning.  Its approximately one quarter mm in diameter, its getting sticky and some brown pus is coming out of it at a very slow rate.  My lips are kind of dry so I used Chapstick Moisturizer on them after noticing it.  Im not sure if this is something to be concerned about or not.  I dont think I have the HSV-1 Virus and havent kissed a girl for around 2.5 years.  I can send a picture if that would help.  Thanks!

Hello and thanks for consulting Chat Doctor. I have gone through your query. If you can send a picture that would be excellent but for now according your info I would say that I might be the case of oral herpes.It's not like only if you kiss an infected person you will have oral herpes. There are other ways of getting the infection also. You may be able to feel a small bump or hardness in the skin in conjunction with the tingling sensation. Other symptoms may include, itching of the lips or skin around mouth, sore throat, swollen glands, and pain when swallowing, and a fever. Herpes simplex virus is highly contagious, so avoid kissing or other mouth-to-body activities at any time during an outbreak. Also avoid sharing utensils, cups, or straws with other people, and wash dishes and utensils thoroughly with disinfectant soap. Gently washing the blisters with soap and water helps a lot. Wash your hands frequently, and try to avoid touching the sore. Use sunscreen on the lips and other vulnerable areas. Zinc oxide may help prevent outbreaks in people whose outbreaks are triggered by sun exposure. If outbreak lasting more than 2 weeks you should visit a doctor. Hope this answers your queryRegards
