This happens to me all sometimes as well. What i have found out is that it is most likely a urinary tract infection, which is really nothing serious. The solution i use is to drink a whole bottle of cranberry juice and lots of water as well. This cleans out your kidney and should stop the burning. The burning sensation should'nt even barley come back if you drink your days worth of water everyday. Also, make sure you are never holding your bladder because it is really bad for you.

Thanks for the help .
