Hi, for the last 10 years I have been suffering from frequent urination . I got digonsed my self for urine culture , routine , ultra sound , all report are normal.  There is no burning while passing urine . When I put some water on head while bathing I feel to urinate a d urine amount is low. While passing urine I feel some urine is still left and I should sit to pass that urine . After completing urination some drop of urine comes out involuntarily. Please suggest any effective homeopathic medicine.
