Recurrent cold sores: Sometimes cold sores (herpes simplex infections) break through antiviral medication treatments like acyclovir. That can happen because Acyclovir may not be strong enough.

I had a small cold sore and tiny cut on my lip, which was not bleeding. I shared a cigarette with stranger, what sort of diseases i can get?

Rare..: It would be very uncommon to see you infected with any disease just for the fact of sharing a cigarette, unless you knew that this person suffers from a particular disease. Cold sores are very common and will probably go away in a few days. Lip balms will help recover. If no improvement after 10 days, see a doctor. ...Read more

I have some small white/yellowish bumps on the inside, back of my lip. In between my gums and lip line. Painful, bleed sometimes. Canker or cold sore?

I have some small white/yellowish bumps on the inside, back of my lip. In between my gums and lip line. Painful, bleed sometimes. Canker or cold sore?

Aphthous ulcer: It's most likely a canker sore. It is painful, I get them sometimes when I eat acidic foods. You can put some oil of clove on it to numb it. It will burn a bit when you put it on but will go away within a few minutes. If your dentist has a soft tissue laser that can also help with the healing process. It should go away in about a week. Hope this helps!!! ...Read more

My cold sore in the corner of my mouth has scabbed over & is starting to crack and bleed making the healing process take longer. Will neosporin help?

Angular cheilitis?: A sore exactly in the corner of the mouth could be oral herpes (cold sore), but more likely is angular cheilitis, a different problem. It's often due to a superficial yeast infection, and antifungal creams may help. Neosporin probably won't help much. See your doctor and take it from there. Good luck! ...Read more
