Hello, I believe I have a candida problem, and have occasional pain in my penis testicles and rectum and other parts of my body. It went away for a while, but then immediately came back the day after I did some heavy drinking. I also noticed a single, red spot, not a bump but just spot at the very opening of my penis. And another thing I noticed was that my penis feels stiff/hard even when I am flaccid. I have also just been diagnosed with mono, of there is anything you think you I could have, please let me know?
