All prostate conditions ruled out. no std. when my hemorrhoids flare i get perineal burning(along sides) and urethra stinging,tip of penis burns. why?

There: is not much "space" in the pelvic/perineal space and any INFLAMMATION tends to swell causing pain in adjacent structures...including the seminal vesicles/urethra and nerves going to the penis. In females this is a well established condition termed "Pelvic Congestion:" Hope this helps BTW SITZ BATHS (HOT TUB) are often VERY EFFECTIVE in relieving this clinical situation! Dr Z
