Gonorrhea is probably one of the most famous sexually transmitted diseases but not the most common anymore. It usually presents as a purulent discharge (pus) from either the penis or vagina. It usually begins 2-8 days after intercourse. It is important to treat this as soon as possible because as with all sexually transmitted diseases, it can only get worse. In men, it can climb up the genital or urinary tract and cause prostatitis, epididymitis or orchitis (enlarged and painful testicles- ouch). In women, it can cause cervicitis, urethritis or pelvic inflammatory disease. In either gender, if left untreated it can cause even disseminated disease. This is usually felt as fever, muscle aches and multiple pus filled sores (like bad zits that keeps getting worse). Unfortunately, I must remind you that it can infect the anus or mouth too. (I wonder how that would happen.)
The good news is that this is fairly easily treated. Whew! You will need to see a physician, humbly (or proudly) admit that you may have been exposed and get both an injection (sorry) and take a course of oral antibiotics. Go do it now. Remember, it can only get worse.
