Bro TS, if you are tested positive for gonorrhea, don't worry lah. This disease can be easily treatable. You will likely be offered an antibiotic, either in pill form or by injection. A single dose is usually all that is required, but some antibiotics require longer courses. Common antibiotics for gonorrhea include: Ofloxacin, Cefixine, and Ceftriaxine. So no need to consult any sex disease doctor and go thru 6 months treatment like what bro James said.
If gonorrhea is left untreated, it can cause many problems in both women and men. Firstly, it is likely to cause infertility in men if it is not properly treated. It is also possible for gonorrhea to spread to other parts of the body. It has been known to infect the heart valves and the brain as well as cause joint inflammation.
