About a month ago i started getting a irritating/burning sensation in the tip of my penis, whenever i went to urinate it was hesitant/delayed and stung, it also seemed to dribble for a short period after i urinate too. I went to the doctors and they said it could be UTI or inflammation of some sort, so they gave me a 1 week course of "trimethoprim", this didnt work. I went back to the doctors and this time they said it could be thrush so i was given anti-fungle cream and took the trush pill, about the same time i started eating loads of raw garlic everyday for about a week and things seemed to improve after a while i was fine. this only lasted for about 3-4 days and now its coming back, i really dont know what it is, its irritating, painfull and im quite worried as to what it could be.
I am male 19-20 years of age and of a healthy size and weight.
Iv looked all over the internet and i cant seem to find much other than STD's, prostate issues, diabetics and UTI's (its definitely not an STD)
What could it be, please help ?
