Long-lasting pulse/numbness (2+ months) inside lip and on my chin - Please help!

[gregmurph]

I am a 29 y.o. male and was recently intimate with a woman who I had never met before.   Roughly a week later, I noticed a visible pulsation inside my right lower lip and a pulsation/numbness on the right side of my chin just outside my lip.  There also appears to be a small indentation outside my lip that is skin color with no blistering, puss, redness, or whiteness.  The indentation is maybe 1mm in size and is in roughly the same place as the pulse outside my lip.   I'm not even sure if that was there before the other symptoms developed.   I assumed that I must have contracted oral herpes, which I had never before been exposed to.  However, I HAVE HAD THESE SAME SYMPTOMS FOR 2 MONTHS STRAIGHT and have not had a single herpes sore appear.   There is not a day that has gone by where I haven't noticed a strong pulse inside my lip.  Is it even possible for a herpes outbreak to last 2 months continuously with these types of symptoms?  Is it possible these symptoms are completely unrelated to my physical encounter, and what else could be causing them?   The pulsing is not continuous, and it tends to be greater late in the day and exacerbating after eating.    Also, I do get canker sores, but this is definitely not a problem related to my canker sores.  Any insight would be helpful!

Thanks for taking the time to reply, scottma.   I failed to mention that I do have the numbness, tingling, swelling sensations that are typical of a herpes outbreak.    I do understand, though, that this can only be confirmed clinically.

Your descriptions are not consistent with herpes simplex infection. In order to establish clinical diagnosis of herpes, multiple vesicular eruptions are essential, further confirmed by lab test. It appears that there is no clinically visible lesion in the oral cavity.Based on the symptoms presented, my clinical impression is benign vascular lesion.Seeing an oral pathologist or oral medicine specialist is advised.
