I have a sore on my inner lip, and it looks a lot like the hiv mouth sores that i've seen before. i've been super worried all day about it! ?

Can be other: Typical mouth sores are Herpes or Aphthous ulcers. If not sure , see your MD or Dentist. If on shiny wet surface inside lip then most common is Aphthous ulcer. If on firm, dry lip/outer lip then Herpes is most common. Both are viral and can appear when immune system is weakened. Can have either / both without HIV. If at risk, get tested. Good Luck.

Suspicious sore?: Regardless the cause... I would advise you to have the sore in your mouth examined by a dentist or dental specialist (e.g. oral surgeon, OFP). Any suspicious sore that does not resolve itself in 2-3 weeks should be evaluated. In the meantime, quit smoking.
