I posted over a year ago on here, and then bookmarked the site. Not sure if anyone is still following, but I found something that fixed my pelvic pains, Cialis.
I'm 36 and had to go see the urologist (a new one) recently about frequent urination at night, which had just started. I had seen three urologist prior to this regarding the pains, and the only thing that worked was taking 1200-1600 mgs of ibuprofen prior to ejaculation, which was neither convenient nor sustainable. I had pretty much given up on the pelvic pain thing, but I brought it up to the new urologist anyway and he thought the two might be related. After a couple of different treatments, an ultrasound, a cystoscopy, and a pelvic/abdomen x-ray, he found nothing and was almost stumped. He finally thought I might try Cialis.

They even prescribe it to pregnant women.
Anyway, I took 5 mg daily for about a week, and both the urination and the pelvic pains post ejaculation went away. I stayed on it for about three months and had no issues.
