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?
