hello, i beleive i have a UTI but im not quite sure, im 21, sexually active, a few days ago i got a sudden sensation when i finished using the toilet, its not exactly a burning feeling though. then it dissapeared the day after, now i have the feeling again but its not the same as before, its just like an uncomfortable felling constantly, not a burning feeling but just something that you know is there and you can feel it, can you make out what it could be?
