What are the effective treatment options for chronic rectal and prostate pain?

Hello doctor,

I am a 20-year-old male with a height of 6.1 feet and a weight around 132 pounds. I have been experiencing persistent issues related to my rectum or prostate for the past few years. This problem initially arose during sexual intercourse when I experienced discomfort at the point of ejaculation. I initially dismissed it as a minor issue but sought medical help from two different urologists, both of whom found no abnormalities upon examining my rectum and prostate. They prescribed medication to be taken with food, which has since become ineffective. I am in search of a permanent solution. I recently discovered that there is a history of colon cancer on my father's side of the family. However, a blood test performed by the doctors showed no apparent issues. To describe the pain, it has become more noticeable, particularly upon arousal. It originates from the rectum and extends upward to my stomach, just above the pubic area below the belly button. The rectal discomfort feels like intense aching and throbbing, almost like a sharp pinch, while the lower stomach pain feels similar to being punched. This pain has escalated over time, and I am concerned about its progression. The doctors inquired about urinary issues, such as leakage or difficulty urinating, which have indeed become problems occurring every other day. I am hopeful that you can offer assistance in resolving this situation, which has persisted for nearly two years and is steadily worsening. Kindly help.
