What causes burning sensation after urinating and sex?
Patient: I am a male and have burning sensation after urinating and sex.  I also have a small bit of discomfort on my lower abdominal and dont have a noticable discharge, but do feel like i am constantly wet.  I have test negative for STD's ( particular Chlymedia and Ghonoria). My symptons had started in February, shortly after i had unprotected sex. I had consulted 2 docters that had both indicated that i might be just an irrative bowl and blood test do show that i dont have any infection (red and white blood cell counting). I can def feel that something is not right and dont know how to re-explain it to determine to cause for my concern or for what other possible infection i can test for.  What else can cause the indicate symptones and for what other diseases can i ask to be tested for? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  The most common cause for burning and itching or pain after sex or urination is lower urinary tract infection which includes prostatitis,urethritis or cystitis, i would recommend you to get your urine complete examination done and see if it shows any infection but in most of the cases the burning is due to urethritis which would not show any infection on urine complete. I would start you on antibiotic from quinolone group like levofloxacin for one day along with cranberry extract juice to reduce the burning.  Hope I have answered your query. Let me know if I can assist you further.
