Hello. Two weeks ago I noticed a large bump on the shaft of my penis. It got smaller and smaller over the next 5 days, it appeared it was going away, however it never completely did. Yesterday it is now large again, back to the size it was 2 weeks ago. It is A pimple like bump. Not painful. Im worried this is primary syphillis. I have had sex with multiple partners, but I used a condom every time. I have recieved oral with no condom. I have gotten a pimple on my penis before i became sexually active, but it was much smaller. I will try to attach a picture. What does it sound like to you? If it sounds like syphillis, will clinicians treat righ away or require a confirmatory test? The cost will all be on me so i hope they will just treat.
