Hi, I m a 25 year old male with concerns over my diagnosis of prostatitus. In May I had a potentially risky sexual encounter that involved both giving and receiving oral sex. A few days after I experienced testicular pain accompanied by flu-like symptoms of fever, body-aches and night sweats with an extremely sore throat. Went to a minor emergency center which prescribed me azithromycin as well as a steroid pack. However after taking the medication I still had symptoms of a general discomfort in my genital area and an itchy anus/perinium. After still feeling these symptoms I got tested for stds doing a 10 panel confidential online test (not sure how reliable those are) but everything came back negative. After still having lower abdominal pain and itching of the anus with testicular discomfort I visited the family doctor who also administered hiv/std testing which also came back negative. My doctor then referred me to a urologist who examined my prostate and excreted urine from massaging the prostate which is currently being cultured. In the meantime, the urologist prescribed me Bactrim DS to take for a 4 week cycle. After a week of taking bactrim I missed a dose and broke out in hives (first allergic reaction in my life and am not sure if it s related to taking the antibiotics). However I m still feeling a general discomfort in my lower abdomin and testicles and the itching in my anus has worsened. So my questions are, should I continue this cycle of antibiotics if I m possibly allergic, or take another antibiotic such as cipro instead? Also do I have any reason to doubt the results of the std testing given the timeframe was about three-four weeks after the possible exposure? Any help and advice is greatly appreciated.
