ick.
well for me it always goes away in a couple of weeks at the most
maybe you should get it checked out again
you can get bladder stones (like kidney stones, but they form in your bladder) and i could be totally wrong, im not really sure, but i think one of the symptoms of that is feeling like you need to pee all the time
look it up and see.
i know how uncomfortable it is even for a week, over a month.. yikes. i really dont know.
