Symptoms:feels like urine leaking, but not, always burning sensation in the pubic bone and penis, mild burning sensation while urinating?

Talk with doctors... Your available information indicates you have already received substantial evaluation and rx. So, it would be advisable to continue the communication and discussion with your existing doctor for further care. But for the time being, i advise behavioral modification in watching what you drink and eat, voiding regularly, gentle urethral milking after each voiding to clear urine... Best wishes...
