How early can a syphilis sore appear?

I am a 20 year old straight man. I have tested negative for most of the scary stds. However, last friday, 4/3/2015, I had a bit much to drink and remember putting myself to bed. I woke up to find my door open and my mates proceeded to make up stories about me blacking out and fighting people, smoking and 'talking' with a gay black man. After causing me a bit of stress by insinuating that I slept with this fictitious man, they finally told they made it up and I forgave them. However for the last couple days i have noticed an odd pink/red lump right below the head. I am now worried that it may be syphilis. It is not very firm and has appeared with 4-5 days after the encounter. The extreme lack of incubation time from the average 21 days is what concerns me most. I am seeing a doctor about this, I just want to know your opinions.

Thanks I am beginning to believe that it is actually a friction burn as I have gotten one in that area before.

If you didn't do anything, then no problem. Anyway, 4 days is too early for a syphilitic sore and it wouldn't appear on your head, no way.

I also assumed that I blacked out and got out of bed. That is why I was so unsure if I had done anything the night before even though I'm fairly sure nothing did

I have no real clue why I am so concerned, all i have noticed is a red spot/lump beneath the head. I have no idea how long its been there

Your mates are really funny! 5 days is too early for a chancre and it wouldn't appear on the head but if you didn't have sex with anyone, why are you concerned?
