I am 42 years female with two kids (17,13) by cesarean .first kid in2005 and second one 2009. From 2014 I am having recurrent uti, s.culture always comes positive with e.coli.thousands of tests are done all are o.k. No sugar, diabetes, cancer ,tb. Done with all kinds of ultra sounds but nothing comes still mostly after two months I get one uti. Taken antibiotics as prophylactic dose. For 3 months still nothing. And one more thing I have right labia minora lip larger than left. And after 2 /3 years I had a bump on it at opening of urethra on labia minora. Visited many gynaecologist they said it's nothing but due to sebaceous duct closed. When it filled with pus they just pop it prescribed me with oflox200 and tbact ointment. And warm compressions. Then it's go away.
