From around 2 months finding difficult to urinate and during passing urine until fart comes unable to pass urine. Frequency for passing urine has increased. Though have tried to avoid drinking water in office or while traveling, feeling too much uncomfortable because of frequent urine temptation. Today while passing motion too much blood went out and I'm worried and afraid due to this. Please suggest which doctor I should consult and how to come out of this problem. Thanks in advance.
