I m 27 years old male. 3 weeks before I had sex with one unknown guy without condom. Now I found a painless sore on my penis shaft ( inside of foreskin ).
When I consulted a doctor she prescribed to take 3 Amoxicillin (500mg) per day for 5 days and a cream to apply on the sore but I didn't tell her that I had sex with a guy.
5 days not yet completed.This is 3rd day but I feel sore is getting dry now.
My question is,
1. Is this sore related to syphilis or allergy sore?
2. Will cure Amoxicillin for both infection?
