I have had a pain in my penis head for a while now. Every time I sit, it becomes increasingly more painful. Also, when I finish urinating, it takes a while for it to stop dribbling, which has never happened before. And by a while, I mean minutes, and it's difficult for me to stop dribbling. There also appears to be bumps around the tip of the penis head, which I assumed were bumps, but my dermatologist wrote them off as "engorged veins"? I've never heard of that before? Also, these bumps, veins, or whatever, they do not burst, have puss, they don't change formation, and they haven't gone away in MONTHS... Anyways, the pain is centralized in that same area, and can become quite severe. I don't know what to do. I've seen three urologists, two dermatologist, and a handful of other doctors. They have tested me for STDs, have done cultures, have tested my urine for UTIs and STIs and everything comes back negative. I have also been tested for yeast, and diabetes, and they have come back negative/normal as well. I have posted a photo of the infected, painful area. I really need some advice. Should I have my PCP check my prostate?? perform a digital rectal examination?? pleeeease heeeeeelp
