[|Human|] For the past 1 1/2 weeks Ive had what I thought was a canker sore on my inferior labial frenulum. It hurts so much, to eat, and drink anything. I now noticed its got a small cut on it and is white. Ive tryed warm water and salt rinsing but i dont see any improvement. Please help me!
[|AI|]  HiT hank you for asking ChatDoctorI have gone through your query. Chancre sore is due to primary syphilis. Do you have any unprotected sexual intercourse? If you send a picture then it will be more helpful in identifying. Dark field microscopy from the lesion will help to confirm it. If it is that then 1 shot of penicillin G or doxycycline for 1 week orally will be helpful to eradicate infection and sore. Hope this may help you. Let me know if anything is not clear. Thanks.
