Hi there. I am concerned because a single small bump appeared on my penis a few days ago. It has now gotten larger, darker, and it is sore. It is more like a wart or chancre now. I am really concerned that I may have syphilis. Can anyone help me? Thanks,Ryan
Syphilis is now less common in the West, but it's still around. It needs a proper pathology lab test. There are other things a pimple can be, including an ordinary zit, so you need to see a doctor to tell.Syphilis chancres are usually described as painless, though I'm not sure that's a guarantee.
