I have a weird bruising on my lip – I

Patient: I have a weird bruising on my lip – I have never had it before. Looking closer at it – there are weird small white bumps (very very small). I have hooked up with two guys within the past few days and I am not sure if this is due to lots of kissing or from oral sex. I just want to make sure it is not an STD. HELP!

Symptoms: Bruise on lips
