Good morning Dr. My sister have a symptom that she feel she can t empty bladder completely, she have to stay very long time in toilet to try empty her bladder. She said that is why she have to go toilet very often. Many Dr said she has overactive bladder and give many tablets for that symptom But she said all that tablets make he getting worse as she can t pass the urine at all which make her very uncomfortable. Please give us an advice. Thank you. Thi
