Last night a guy came in the ER complaining of an erection that lasted for 12 hours. Turns out that he is taking Sust and Viagra. We had to put a 16 guage needle down his urethra, lance(cut) the base of the penis, and "milk" it to get the coagulated blood out. He has a 50% chance of being impotent.
The patient even said that he had jacked off multiple times to get it to go down without any luck. It was nasty.
Moral of the story: Don't take viagra while on juice(test)!
